    Description: Frames designed for continuous surveys are sometimes used for ad hoc surveys which require selection of sampling units separate from those selected for the continuous survey. This paper presents an unbiased extension of Keyfitz’s (1951) sample updating method to the case where a portion of the frame has been reserved for surveys other than the main continuous survey. A simple although biased alternative is presented.

    The scope under Platek and Singh’s (1975) design strategy for an area based continuous survey requiring updating is then expanded to encompass rotation of first stage units, establishment of a separate special survey sub-frame, and procedures to prevent re-selection of ultimate sampling units.

    The methods are evaluated in a Monte Carlo study using Census data to simulate the design for the Canadian Labour Force Survey.

    Description: Some estimators alternative to the usual PPS estimator are suggested in this paper for situations where the size measure used for PPS sampling is not correlated with the study variable and where data are available on another supplementary variable (size measure). Properties of these estimators are studied under super-population models and also empirically.

  • Articles and reports: 12-001-X197800254830
    Description: The problems of dealing with non-response at various stages of survey planning are discussed with implications for the mean square error, practicality and possible advantages and disadvantages. Conceptual issues of editing and imputation are also considered with regard to complexity and levels of imputation. The methods of imputation include weighting, duplication, and substitution of historical records. The paper includes some methodology on the bias and variance.

    Description: When a two-stage sample is used to collect data, the correlations between the sampled units make the ?2 test of independence invalid. Use of the ordinary ?2 tables generally results in a test which is greater than the desired level of significance. The effect of the sample design comes from two main areas: the sample size within PSU’s and the degree to which the characteristics are independent within each PSU. The effect of the sample size within PSU’s is greatest when there is no independence within each PSU, and diminishes as the degree of independence increases.

    Description: The impact on linear statistics of the sample design used in obtaining survey data is the subject of much of sampling literature. Recently, more attention has been paid to the design’s impact on non-linear statistics; the major factor inhibiting these investigations has been the problem of estimating at least the first two moments of such statistics. The present article examines the problem of estimating the variances of non-linear statistics from complex samples, in the light of existing literature. The behaviour of the chi-square statistic computed from a complex sample to test hypotheses of goodness of fit or independence is studied. Alternative tests are developed and their properties studied in simulation experiments.

    Description: This paper describes a survey design established to measure truck commodity flows in Peru. The article addresses the conceptual and operational features of the survey design as well as describing its elements and implementation techniques in the context of a pilot project. Finally, the paper illustrates how the results of this pilot might be used to design and implement a full-scale national survey.

    Description: The total variance of a survey estimate incorporates sampling variance, simple response variance and correlated response variance. The last component reflects the part of the total variance due to a common influence on a group of respondents. In the Canadian census, self-enumeration was adopted as the standard method of enumeration in the 1971 Census. One factor in favor of introducing this method was evidence, from the 1961 Census, that correlated response variance made an important contribution to the total variance of census estimates. Based on a study conducted using interpenetration of interviewers, this article compares correlated response variances from the 1961, 1971 and 1976 Censuses. The empirical results demonstrate that although the self-enumeration adopted in the 1971 Census did not completely remove the correlated response variance, this approach has considerably reduced the magnitude of this component of variance for almost all the characteristics examined.

    Description: This article presents the findings of an experimental design set up to study the variation in refusal rates to the different modules of the physical measures component of the Canada Health Survey. The study indicated that interviewer teams have a significant impact on refusal rates. Also, a large proportion of the refusals was due to total family refusals rather than individual refusals within responding families.

    Description: Raking ratio estimators give estimates of the population values of characteristics examined on a sample basis utilizing the row and column totals of a contingency table of characteristics examined on a 100% basis. In this paper, the asymptotic variance of the maximum likelihood estimator of a sample characteristic subject to the marginal constraints of the above contingency table is derived. From this, we are able to compute the loss in efficiency of the raking ratio estimators relative to the maximum likelihood estimator in an empirical study.
