  • 1. Aboriginal data initiative: Survey component Archived
    Articles and reports: 11-522-X20040018655
    Description:

    The design of surveys for Aboriginal groups brings challenges: identification of the target population, challenges in survey design, remoteness and response burden.

    Release date: 2005-10-27
  • 2. Methodological challenges in a survey on the ethnic and cultural diversity of the Canadian population Archived
    Articles and reports: 11-522-X20040018734
    Geography: Canada
    Description:

    The Ethnic Diversity Survey generated methodological challenges like choosing the sampling plan, developing the questionnaire, collecting the data, weighting the data and estimating the variance.

  • 3. A multivariate analysis of nonresponse among ethnic minorities Archived
    Articles and reports: 11-522-X20040018735
    Description:

    This paper describes analyses on nonresponse among ethnic minorities in the Netherlands. These analyses show that the response effect is mediated by the degree of urbanisation. A negative impact is observed among ethnic minorities.

    Release date: 2005-10-27
  • 4. Improving the quality of estimates for a low-income population: Use of a dual frame in the survey of household spending Archived
    Articles and reports: 11-522-X20040018753
    Description:

    For the estimation of low-income households, a supplementary sample is selected within a limited number of geographic areas. This paper presents the dual sample design used, along with scenarios considered and some findings that led to the choices made.

    Release date: 2005-10-27
  • 5. Challenges in the survey of electronic commerce and technology Archived
    Articles and reports: 11-522-X20040018754
    Description:

    For the Survey of Electronic Commerce and Technology, studies are required on rare-event estimation. This paper describes the survey, its main problems and challenges, study findings, and past and future actions.

  • 6. Whither the workweek? Archived
    Articles and reports: 75-001-X200510613145
    Geography: Canada
    Description:

    Changes in hours worked normally track employment changes very closely. Recently, however, employment has increased more than hours, resulting in an unprecedented gap. In effect, the average annual hours worked have decreased by the equivalent of two weeks. Many factors can affect the hours worked. Some are structural or cyclical - population aging, industrial shifts, the business cycle, natural disasters, legislative changes or personal preferences. Others are a result of the survey methodology. How have the various factors contributed to the recent drop in hours of work?

  • 7. Editing systematic unity measure errors through mixture modelling Archived
    Articles and reports: 12-001-X20050018087
    Description:

    In Official Statistics, data editing process plays an important role in terms of timeliness, data accuracy, and survey costs. Techniques introduced to identify and eliminate errors from data are essentially required to consider all of these aspects simultaneously. Among others, a frequent and pervasive systematic error appearing in surveys collecting numerical data, is the unity measure error. It highly affects timeliness, data accuracy and costs of the editing and imputation phase. In this paper we propose a probabilistic formalisation of the problem based on finite mixture models. This setting allows us to deal with the problem in a multivariate context, and provides also a number of useful diagnostics for prioritising cases to be more deeply investigated through a clerical review. Prioritising units is important in order to increase data accuracy while avoiding waste of time due to the follow up of non-really critical units.

  • 8. Approximations to b* in the prediction of design effects due to clustering Archived
    Articles and reports: 12-001-X20050018093
    Description:

    Kish's well-known expression for the design effect due to clustering is often used to inform sample design, using an approximation such as b_bar in place of b. If the design involves either weighting or variation in cluster sample sizes, this can be a poor approximation. In this article we discuss the sensitivity of the approximation to departures from the implicit assumptions and propose an alternative approximation.

  • 9. A note on the C_P statistic under the nested error regression model Archived
    Articles and reports: 12-001-X20050018094
    Description:

    Nested error regression models are frequently used in small-area estimation and related problems. Standard regression model selection criterion, when applied to nested error regression models, may result in inefficient model selection methods. We illustrate this point by examining the performance of the C_P statistic through a Monte Carlo simulation study. The inefficiency of the C_P statistic may, however, be rectified by a suitable transformation of the data.

  • 10. Comparing a rate in a subpopulation to the rate in the full population: How it may be done when using survey data, and available software tools Archived
    Articles and reports: 12-002-X20050018030
    Description:

    People often wish to use survey micro-data to study whether the rate of occurrence of a particular condition in a subpopulation is the same as the rate of occurrence in the full population. This paper describes some alternatives for making inferences about such a rate difference and shows whether and how these alternatives may be implemented in three different survey software packages. The software packages illustrated - SUDAAN, WesVar and Bootvar - all can make use of bootstrap weights provided by the analyst to carry out variance estimation.

Search help

How do I use the filters and the search box?

  • You can initiate a search by entering keywords or selecting filters (e.g., under Subject, Geography, etc.) on the left side of the page.

  • Filters can be used together or in any combination. Each time you select a filter, the results on the page are updated.

  • To start a new search, click on the Clear all button above the search box or deselect each filter.

  • Specified keywords and filters appear above the search box. You can deselect any or all the tags to refine or clear your search.

How do I refine my search?

  • You can enter keywords in the search box. It is not necessary to use “+” or “, “ or “AND”.

  • You can delete some or all of the keywords from your search string.

  • Quotes around keywords limit the search to a specific phrase.

    • For example, “labour force survey” will limit results to products containing this phrase.

  • Use “or” between keywords to obtain results that contain one or more search terms.

    • For example, labour or­ force or survey will limit results to products containing any or all of these words.

How does the search work?

  • This search looks for results that have your query term in the title, description, subject, geography, product number or other information about the product.

    • For example, when searching the term ‘Diseases’, all results with the word ‘Diseases’ in the title, description or tagged the subject appear.

  • The text within an article or publication are not searched. For full text searching of articles, use the site search.

Sort help

How are the results ordered?

The Sort by feature provides three options:

  • By date – sorts results by product release date starting with the most recent.
  • By relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.
  • By title – sorts results alphabetically.

Sort help

How are the results ordered?

The Sort by feature provides four options:

  • By date – sorts results by product release date starting with the most recent.
  • By most popular – gives priority to results that are most frequently selected by users, followed by the most recent.
  • By relevance is only needed or beneficial when you use the search box and submit a search query. Results are ordered by a combination of where the search term appears in the content, e.g., if it appears in the title, it likely means the product is more relevant to your search; how up to date or new the content in the product is; how popular the product is; and other factors.
  • By title – sorts results alphabetically.
