Félix-Medina and Thompson (2004) proposed a variant of link-tracing sampling to sample hidden and/or hard-to-detect human populations such as drug users and sex workers. In their variant, an initial sample of venues is selected and the people found in the sampled venues are asked to name other members of the population to be included in the sample. Those authors derived maximum likelihood estimators of the population size under the assumption that the probability that a person is named by another in a sampled venue (link-probability) does not depend on the named person (homogeneity assumption). In this work we extend their research to the case of heterogeneous link-probabilities and derive unconditional and conditional maximum likelihood estimators of the population size. We also propose profile likelihood and bootstrap confidence intervals for the size of the population. The results of simulations studies carried out by us show that in presence of heterogeneous link-probabilities the proposed estimators perform reasonably well provided that relatively large sampling fractions, say larger than 0.5, be used, whereas the estimators derived under the homogeneity assumption perform badly. The outcomes also show that the proposed confidence intervals are not very robust to deviations from the assumed models.

The University of Wisconsin Cancer Intervention and Surveillance Modeling Network breast cancer microsimulation model was adapted to simulate breast cancer incidence and screening performance in Canada. The model considered effects of breast density on the sensitivity and specificity of screening. The model’s ability to predict age-specific incidence of breast cancer was assessed.
Release date: 2015-12-16 - Articles and reports: 82-003-X201501214294Description:
This analysis employs a validated microsimulation model of breast cancer, adapted to the Canadian context, to predict health outcomes associated with different digital mammography screening strategies (including No Screening) across different age ranges. The model estimates the benefits, harms, limitations, and use of resources for each strategy.
Release date: 2015-12-16 - 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.
Release date: 2015-12-16 - Articles and reports: 11F0019M2015372Description: This paper presents a growth accounting framework in which subsoil mineral and energy resources are recognized as natural capital input into the production process. It is the first study of its kind in Canada. Firstly, the income attributable to subsoil resources, or resource rent, is estimated as a surplus value after all extraction costs and normal returns on produced capital have been accounted for. The value of a resource reserve is then estimated as the present value of the future resource rents generated from the efficient extraction of the reserve. Lastly, with extraction as the observed service flows of natural capital, multifactor productivity (MFP) growth and the other sources of economic growth can be reassessed by updating the income shares of all inputs, and then, by estimating the contribution to growth coming from changes in the value of natural capital input. This framework is then applied to the Canadian oil and gas extraction sector.Release date: 2015-12-14
- Articles and reports: 89-653-X2015007Description:
Within the last decade, Inuit Tapiriit Kanatami has identified mental wellness as the single most important health issue for Inuit (Alianait Inuit-specific Mental Wellness Task Group, 2007). Understanding the complex arrangements of circumstances, behaviours and relationships that are associated with mental health—often termed social determinants—may provide a window for policy makers in addressing mental distress among Inuit.
Using the 2012 Aboriginal Peoples Survey, this study examines the social determinants of higher mental distress among Inuit aged 18 years and over, living in Inuit Nunangat. Mental distress was studied using the ten-item Kessler distress scale (K10); and multivariate analysis was conducted using a logistic regression model.
Release date: 2015-11-17 - 7. Youth court statistics in Canada, 2013-2014 ArchivedArticles and reports: 85-002-X201500114224Description:
This Juristat examines the number and types of cases completed in youth courts on an annual basis. Characteristics of youth accused, case decisions, types of sentences imposed and case completion times are also explored. Data are presented at both the national and provincial/territorial levels.
Release date: 2015-09-28 - 8. Retail: The Year 2014 in Review ArchivedArticles and reports: 11-621-M2015096Description:
Using data from the Monthly Retail Trade and Quarterly Retail Commodity surveys, this study examines the sales for the year 2014. This annual review describes sales growth and trends by subsectors such as motor vehicle and parts dealers, food and beverage stores and general merchandise stores. This study also discusses provincial retail sales.
Release date: 2015-08-04 - Articles and reports: 82-003-X201500714204Description:
The objective of this study was to determine if the prevalence of overweight and obesity is associated with neighbourhood walkability. The analysis tested whether a dose-response relationship between the Street Smart Walk Score® and various measures of physical activity, overweight, and obesity existed in a large, population-based sample of adults in urban and suburban Ontario.
Release date: 2015-07-15 - 10. Police-reported hate crime in Canada, 2013 ArchivedArticles and reports: 85-002-X201500114191Description:
This Juristat article examines the nature and extent of police-reported hate crime in Canada. Key topics include motivations for hate crime (e.g. race/ethnicity, religion, and sexual orientation), types of offences, geographical comparisons and accused/victim characteristics. The article uses data from the Incident-based Uniform Crime Reporting Survey which gathers data from police records.
