Description:

In this paper, we study the problem of variance estimation for a ratio of two totals when marginal random hot deck imputation has been used to fill in missing data. We consider two approaches to inference. In the first approach, the validity of an imputation model is required. In the second approach, the validity of an imputation model is not required but response probabilities need to be estimated, in which case the validity of a nonresponse model is required. We derive variance estimators under two distinct frameworks: the customary two-phase framework and the reverse framework.

The Australian Bureau of Statistics has recently developed a generalized estimation system for processing its large scale annual and sub-annual business surveys. Designs for these surveys have a large number of strata, use Simple Random Sampling within Strata, have non-negligible sampling fractions, are overlapping in consecutive periods, and are subject to frame changes. A significant challenge was to choose a variance estimation method that would best meet the following requirements: valid for a wide range of estimators (e.g., ratio and generalized regression), requires limited computation time, can be easily adapted to different designs and estimators, and has good theoretical properties measured in terms of bias and variance. This paper describes the Without Replacement Scaled Bootstrap (WOSB) that was implemented at the ABS and shows that it is appreciably more efficient than the Rao and Wu (1988)'s With Replacement Scaled Bootstrap (WSB). The main advantages of the Bootstrap over alternative replicate variance estimators are its efficiency (i.e., accuracy per unit of storage space) and the relative simplicity with which it can be specified in a system. This paper describes the WOSB variance estimator for point-in-time and movement estimates that can be expressed as a function of finite population means. Simulation results obtained as part of the evaluation process show that the WOSB was more efficient than the WSB, especially when the stratum sample sizes are sometimes as small as 5.

Description:

The purpose of this work is to obtain reliable estimates in study domains when there are potentially very small sample sizes and the sampling design stratum differs from the study domain. The population sizes are unknown as well for both the study domain and the sampling design stratum. In calculating parameter estimates in the study domains, a random sample size is often necessary. We propose a new family of generalized linear mixed models with correlated random effects when there is more than one unknown parameter. The proposed model will estimate both the population size and the parameter of interest. General formulae for full conditional distributions required for Markov chain Monte Carlo (MCMC) simulations are given for this framework. Equations for Bayesian estimation and prediction at the study domains are also given. We apply the 1998 Missouri Turkey Hunting Survey, which stratified samples based on the hunter's place of residence and we require estimates at the domain level, defined as the county in which the turkey hunter actually hunted.

Description:

The European Community Household Panel (ECHP) is a panel survey covering a wide range of topics regarding economic, social and living conditions. In particular, it makes it possible to calculate disposable equivalized household income, which is a key variable in the study of economic inequity and poverty. To obtain reliable estimates of the average of this variable for regions within countries it is necessary to have recourse to small area estimation methods. In this paper, we focus on empirical best linear predictors of the average equivalized income based on "unit level models" borrowing strength across both areas and times. Using a simulation study based on ECHP data, we compare the suggested estimators with cross-sectional model-based and design-based estimators. In the case of these empirical predictors, we also compare three different MSE estimators. Results show that those estimators connected to models that take units' autocorrelation into account lead to a significant gain in efficiency, even when there are no covariates available whose population mean is known.

Description:

Coverage deficiencies are estimated and analysed for the 2000 population census in Switzerland. For the undercoverage component, the estimation is based on a sample independent of the census and a match with the census. For the overcoverage component, the estimation is based on a sample drawn from the census list and a match with the rest of the census. The over- and undercoverage components are then combined to obtain an estimate of the resulting net coverage. This estimate is based on a capture-recapture model, named the dual system, combined with a synthetic model. The estimators are calculated for the full population and different subgroups, with a variance estimated by a stratified jackknife. The coverage analyses are supplemented by a study of matches between the independent sample and the census in order to determine potential errors of measurement and location in the census data.

Description:

In this paper we describe a methodology for combining a convenience sample with a probability sample in order to produce an estimator with a smaller mean squared error (MSE) than estimators based on only the probability sample. We then explore the properties of the resulting composite estimator, a linear combination of the convenience and probability sample estimators with weights that are a function of bias. We discuss the estimator's properties in the context of web-based convenience sampling. Our analysis demonstrates that the use of a convenience sample to supplement a probability sample for improvements in the MSE of estimation may be practical only under limited circumstances. First, the remaining bias of the estimator based on the convenience sample must be quite small, equivalent to no more than 0.1 of the outcome's population standard deviation. For a dichotomous outcome, this implies a bias of no more than five percentage points at 50 percent prevalence and no more than three percentage points at 10 percent prevalence. Second, the probability sample should contain at least 1,000-10,000 observations for adequate estimation of the bias of the convenience sample estimator. Third, it must be inexpensive and feasible to collect at least thousands (and probably tens of thousands) of web-based convenience observations. The conclusions about the limited usefulness of convenience samples with estimator bias of more than 0.1 standard deviations also apply to direct use of estimators based on that sample.

Description:

The recent economic boom in the Canadian province of Alberta provides an ideal "natural experiment" to examine immigrants' responses to a strong labour demand outside major metropolitan centres. The key finding of our study, which is based on a unique dataset that combines administrative and immigrant records, is that not only did immigrants respond to the recent economic boom in Alberta, but they responded generally more strongly than non-immigrants. We find, however, a great deal of heterogeneity in the magnitude of the response across different regions and for different categories of immigrants.

The Internet's rapid and profound entry into our lives quite understandably makes people wonder how, both individually and collectively, we have been affected by it. When major shifts in technology use occur, utopian and dystopian views of their impact on society often abound, reflecting their disruptiveness and people's concerns. Given its complex uses, the Internet, both as a technology and as an environment, has had both beneficial and deleterious effects. Above all, though, it has had transformative effects.

Are Canadians becoming more isolated, more reclusive and less integrated in their communities as they use the Internet? Or, are they becoming more participatory and more integrated in their communities? In addition, do these communities still resemble traditional communities, or are they becoming more like social networks than cohesive groups?

To address these questions, this article organizes, analyzes and presents existing Canadian evidence. It uses survey results and research amassed by Statistics Canada and the Connected Lives project in Toronto to explore the role of the Internet in social engagement and the opportunities it represents for Canadians to be active citizens. It finds that Internet users are at least as socially engaged as non-users. They have large networks and frequent interactions with friends and family, although they tend to spend somewhat less in-person time and, of course, more time online. An appreciable number of Internet users are civically and politically engaged, using the Internet to find out about opportunities and make contact with others.

Description:

This paper compares the productivity growth of a set of Canadian and U.S. regulated industries. Using data from Statistics Canada's KLEMS database and the U.S. Bureau of Economic Analysis, the paper examines productivity growth in transportation services (which includes air and rail), broadcasting and telecommunications, and financial services (which includes financial intermediation and insurance), over the period from 1977 to 2003. The majority of these provide the foundational networks on which other industries rely. These sectors were quite heavily regulated in Canada at the beginning of the period of study (1977), experienced partial deregulation during the period and still faced various types of regulation at the end (2003). Deregulation also occurred in the United States, but regulation has generally been less restrictive there over most of the period.

The evidence shows that many of the Canadian industries that underwent deregulation experienced faster labour productivity growth and multifactor productivity growth than did the aggregate Canadian business sector and had similar or higher productivity growth than did their counterparts in the United States over the 1977-to-2003 period. Those industries include rail transportation, broadcasting and telecommunications, financial intermediation and insurance carriers. The airline industry had slower productivity growth in Canada than in the United States over the 1977-to-2003 period.
