  • Articles and reports: 12-001-X198100154932
    Description:

    The methodology of the For-hire Trucking Survey is discussed in this paper. This survey provides good examples of administrative and operational constraints faced by survey statisticians and field data collection teams.

  • Articles and reports: 12-001-X198100154935
    Description:

    A FORTRAN Subroutine to obtain the “working probabilities” for Fellegi’s (1963) method of unequal probability sampling is given. The solution is obtained by an iterative procedure where the starting values for the (k+l)th draw “working probabilities” are the solutions for the kth draw “working probabilities” and the iterative procedure is terminated when a prespecified accuracy is achieved. The limitation is that the Subroutine can only be used to obtain up to and including the 5th draw “working probabilities”. It was observed that the convergence occurs very fast in double precision. Therefore all real variables have been declared as double precision. The joint selection probabilities \Pi_{ij}’s i.e. the probability that both the ith and jth units are in the sample are obtained by summing the probabilities of selecting those samples that contain both the ith and jth units. The joint selection probabilities are required for the variance estimation of the Horvitz-Thompson estimator of population total of the characteristic of interest.

    Description:

    Survey organizations undertake periodic redesigns of continuous surveys. Reasons for such redesigns related to changes in information needs to be satisfied by the survey and changes in public awareness and attitudes towards surveys are discussed in the context of the redesign of the Canadian Labour Force Survey following the 1981 Census. In particular, the importance of close dialogue between users of the survey data and design statisticians at the early stages of the redesign process in order to establish survey objectives is stressed.
