- 1. Statistics 101: Exploring measures of dispersion ArchivedStats in brief: 89-20-00062020003Description:
In this module, we will explore the concept of dispersion, also called variability. This concept includes: the range, the interquartile range, the standard deviation and the normal distribution.
Release date: 2021-05-03 - 2. The DYSEM Microsimulation Modelling Platform ArchivedArticles and reports: 11-633-X2017008Description:
The DYSEM microsimulation modelling platform provides a demographic and socioeconomic core that can be readily built upon to develop custom dynamic microsimulation models or applications. This paper describes DYSEM and provides an overview of its intended uses, as well as the methods and data used in its development.

The estimation of quantiles is an important topic not only in the regression framework, but also in sampling theory. A natural alternative or addition to quantiles are expectiles. Expectiles as a generalization of the mean have become popular during the last years as they not only give a more detailed picture of the data than the ordinary mean, but also can serve as a basis to calculate quantiles by using their close relationship. We show, how to estimate expectiles under sampling with unequal probabilities and how expectiles can be used to estimate the distribution function. The resulting fitted distribution function estimator can be inverted leading to quantile estimates. We run a simulation study to investigate and compare the efficiency of the expectile based estimator.

Optimum stratification is the method of choosing the best boundaries that make strata internally homogeneous, given some sample allocation. In order to make the strata internally homogenous, the strata should be constructed in such a way that the strata variances for the characteristic under study be as small as possible. This could be achieved effectively by having the distribution of the main study variable known and create strata by cutting the range of the distribution at suitable points. If the frequency distribution of the study variable is unknown, it may be approximated from the past experience or some prior knowledge obtained at a recent study. In this paper the problem of finding Optimum Strata Boundaries (OSB) is considered as the problem of determining Optimum Strata Widths (OSW). The problem is formulated as a Mathematical Programming Problem (MPP), which minimizes the variance of the estimated population parameter under Neyman allocation subject to the restriction that sum of the widths of all the strata is equal to the total range of the distribution. The distributions of the study variable are considered as continuous with Triangular and Standard Normal density functions. The formulated MPPs, which turn out to be multistage decision problems, can then be solved using dynamic programming technique proposed by Bühler and Deutler (1975). Numerical examples are presented to illustrate the computational details. The results obtained are also compared with the method of Dalenius and Hodges (1959) with an example of normal distribution.

To model economic depreciation, a database is used that contains information on assets discarded by companies. The acquisition and resale prices are known along with the length of use of these assets. However, the assets for which prices are known are only those that were involved in a transaction. While an asset depreciates on a continuous basis during its service life, the value of the asset is only known when there has been a transaction. This article proposes an ex post weighting to offset the effect of source of error in building econometric models.

- 8. Service Inflation: Why Is It Higher? ArchivedArticles and reports: 62F0014M1997005Geography: CanadaDescription:
Since 1961, the service component of the Canadian Consumer Price Index (CPI) has generally shown a higher rate of increase than the goods component. Furthermore, when some of the more volatile components of the CPI are removed the spread widens. For instance, during the same period core goods inflation (excluding food and energy) increased at an annual rate of 4.3% compared to 6.1% per cent for services (excluding shelter). The literature on service sector inflation suggests five explanations for this phenomenon. Although all these sources of the inflation differential are interesting and important in their own right, this paper will examine two. Some believe that service inflation is a statistical artifact stemming from the inherent difficulties in measuring the output of services and hence their price changes. This issue will be examined first. Indeed the measurement problem appears more serious for services; however it cannot be held completely responsible for the inflationary gap. William Baumol (1967) originally suggested the other cause for higher service inflation whereby unbalanced sectorial growth would be the cause of the divergent inflation rates. This explanation will be the focus of the second part of the paper. In spite of the attractiveness of Baumol's model, empirical evidence rejects the hypothesis.
Release date: 1999-05-13 - 9. Job stability ArchivedArticles and reports: 75-001-X19980044042Geography: CanadaDescription:
This article investigates the common claim that jobs are less stable in the service sector. It also contests the view that overall job stability has declined as the economy has shifted toward employment in services. (Adapted from an article in Canadian Economic Observer published in May 1998).
Release date: 1998-12-09 - 10. The declining labour market status of young men ArchivedArticles and reports: 89-553-X19980014019Geography: CanadaDescription:
The goal of this chapter is to document how the young fare in today's labour market. The focus is on young men for two reasons. First, most of the recent literature on the growth of earnings inequality has concentrated on the study of male earnings. This approach is chosen because one of the questions addressed is about the consequences of the growth of earnings inequality on youth age-earnings profiles. Second, and more importantly, the labour market behaviour of women is much more complicated to examine because their participation rates have changed dramatically over the last twenty years.
