Probabilistic linkage is susceptible to linkage errors such as false positives and false negatives. In many cases, these errors may be reliably measured through clerical-reviews, i.e. the visual inspection of a sample of record pairs to determine if they are matched. A framework is described to effectively carry-out such clerical-reviews based on a probabilistic sample of pairs, repeated independent reviews of the same pairs and latent class analysis to account for clerical errors.
Release date: 2016-03-24 - Articles and reports: 82-003-X201501214295Description:
Using the Wisconsin Cancer Intervention and Surveillance Monitoring Network breast cancer simulation model adapted to the Canadian context, costs and quality-adjusted life years were evaluated for 11 mammography screening strategies that varied by start/stop age and screening frequency for the general population. Incremental cost-effectiveness ratios are presented, and sensitivity analyses are used to assess the robustness of model conclusions.

A surveillance tool was developed to assess dietary intake collected by surveys in relation to Eating Well with Canada’s Food Guide (CFG). The tool classifies foods in the Canadian Nutrient File (CNF) according to how closely they reflect CFG. This article describes the validation exercise conducted to ensure that CNF foods determined to be “in line with CFG” were appropriately classified.
Release date: 2015-11-18 - 5. Assessment of the quality of the childhood physical abuse measure in the National Population Health Survey ArchivedArticles and reports: 82-003-X201500514170Description:
All respondents to the National Population Health Survey aged 18 or older were asked a question about childhood physical abuse in cycles 1 (1994/1995), 7(2006/2007) and 8 (2008/2009). The reliability of this question was assessed over these periods. Associations between response patterns to the abuse item and health conditions related to childhood physical abuse were examined.
Release date: 2015-05-20 - Articles and reports: 82-003-X201200111625Geography: CanadaDescription:
This study compares estimates of the prevalence of cigarette smoking based on self-report with estimates based on urinary cotinine concentrations. The data are from the 2007 to 2009 Canadian Health Measures Survey, which included self-reported smoking status and the first nationally representative measures of urinary cotinine.
Release date: 2012-02-15 - Articles and reports: 82-003-X201100111404Geography: CanadaDescription:
This study assesses three child-reported parenting behaviour scales (nurturance, rejection and monitoring) in the National Longitudinal Survey of Children and Youth.
Release date: 2011-02-16 - Articles and reports: 11-522-X200800010955Description:
Survey managers are still discovering the usefulness of digital audio recording for monitoring and managing field staff. Its value so far has been for confirming the authenticity of interviews, detecting curbstoning, offering a concrete basis for feedback on interviewing performance and giving data collection managers an intimate view of in-person interviews. In addition, computer audio-recorded interviewing (CARI) can improve other aspects of survey data quality, offering corroboration or correction of response coding by field staff. Audio recordings may replace or supplement in-field verbatim transcription of free responses, and speech-to-text technology might make this technique more efficient in the future.
Release date: 2009-12-03 - Articles and reports: 11-522-X200800010968Description:
Statistics Canada has embarked on a program of increasing and improving the usage of imaging technology for paper survey questionnaires. The goal is to make the process an efficient, reliable and cost effective method of capturing survey data. The objective is to continue using Optical Character Recognition (OCR) to capture the data from questionnaires, documents and faxes received whilst improving the process integration and Quality Assurance/Quality Control (QC) of the data capture process. These improvements are discussed in this paper.
Release date: 2009-12-03 - Articles and reports: 11-522-X200800010969Description:
In a multi-divisional initiative within the U. S. Census Bureau, a highly sophisticated and innovative system was developed and implemented for the capturing, tracking, and scanning of respondent data that implements Intelligent Character Recognition (ICR), Optical Character Recognition (OCR), Optical Mark Recognition (OMR), and keying technology with heavy emphasis on error detection and control. The system, known as the integrated Computer Assisted Data Entry (iCADE) System, provides digital imaging of respondent questionnaires which are then processed by a combination of imaging algorithms, sent through Optical Mark Recognition (OMR) to collect check box data, and automatically collect and send only write-in areas to data-keying staff for the data capture process. These capabilities have produced great efficiencies in the data capture process and have led to a novel and efficient approach to post-collection activities.

- 1. Particulate matter and daily mortality: Combining time series information from eight U.S. cities ArchivedSurveys and statistical programs – Documentation: 11-522-X19990015656Description:
Time series studies have shown associations between air pollution concentrations and morbidity and mortality. These studies have largely been conducted within single cities, and with varying methods. Critics of these studies have questioned the validity of the data sets used and the statistical techniques applied to them; the critics have noted inconsistencies in findings among studies and even in independent re-analyses of data from the same city. In this paper we review some of the statistical methods used to analyze a subset of a national data base of air pollution, mortality and weather assembled during the National Morbidity and Mortality Air Pollution Study (NMMAPS).
Release date: 2000-03-02 - 2. A donor imputation system to create a census database fully adjusted for underenumeration ArchivedSurveys and statistical programs – Documentation: 11-522-X19990015668Description:
Following the problems with estimating underenumeration in the 1991 Census of England and Wales the aim for the 2001 Census is to create a database that is fully adjusted to net underenumeration. To achieve this, the paper investigates weighted donor imputation methodology that utilises information from both the census and census coverage survey (CCS). The US Census Bureau has considered a similar approach for their 2000 Census (see Isaki et al 1998). The proposed procedure distinguishes between individuals who are not counted by the census because their household is missed and those who are missed in counted households. Census data is linked to data from the CCS. Multinomial logistic regression is used to estimate the probabilities that households are missed by the census and the probabilities that individuals are missed in counted households. Household and individual coverage weights are constructed from the estimated probabilities and these feed into the donor imputation procedure.
Release date: 2000-03-02 - Surveys and statistical programs – Documentation: 11-522-X19990015688Description:
The geographical and temporal relationship between outdoor air pollution and asthma was examined by linking together data from multiple sources. These included the administrative records of 59 general practices widely dispersed across England and Wales for half a million patients and all their consultations for asthma, supplemented by a socio-economic interview survey. Postcode enabled linkage with: (i) computed local road density; (ii) emission estimates of sulphur dioxide and nitrogen dioxides, (iii) measured/interpolated concentration of black smoke, sulphur dioxide, nitrogen dioxide and other pollutants at practice level. Parallel Poisson time series analysis took into account between-practice variations to examine daily correlations in practices close to air quality monitoring stations. Preliminary analyses show small and generally non-significant geographical associations between consultation rates and pollution markers. The methodological issues relevant to combining such data, and the interpretation of these results will be discussed.
Release date: 2000-03-02 - Surveys and statistical programs – Documentation: 11-522-X19980015036Description:
Multivariate logistic regression, introduced by Glonek and McCullagh (1995) as a generalisation of logistic regression, is useful in the analysis of longitudinal data as it allows for dependent repeated observations of a categorical variable and for incomplete response profiles. We show how the method can be extended to deal with data from complex surveys and we illustrate it on data from the Swiss Labour Force Survey. The effect of the sampling weights on the parameter estimates and their standard errors is considered.
