A class of directed acyclic graphs with mixed data types in mediation analysis
Canadian Journal of Statistics, Volume 53, Issue 4, December 2025.Abstract We propose a unified class of generalized structural equation models (GSEMs) with data of mixed types in mediation analysis, including continuous, categorical, and count variables. Such models extend substantially the classical linear structural equation model to accommodate many data types arising from the application of mediation analysis ...

Communications for Statistical Applications and Methods, 2002 In this paper, we considered an application of the bootstrap method for logit model. Estimation of type I error probability, the bootstrap p-values and bootstrap confidence intervals of parameter were proposed. Small sample Monte Carlo simulation were conducted in order to compare proposed method with existing normal theory based asymptotic method.

Latent Ideological Positions of Swiss Parties and Subsets of the Population
Swiss Political Science Review, Volume 31, Issue 4, Page 733-752, December 2025.Abstract Prominent theories of political representation consider ideology to be a central concept that links political elites and citizens. However, studies usually rely on different data and measures to operationalize this concept. This paper presents a two‐step estimation strategy for measuring the ideological positions of parties and population ...

Journal of Animal Ecology, Volume 94, Issue 11, Page 2282-2294, November 2025.We show that Arctic and red fox space use significantly affects goose nest habitat selection and nest success in a low‐Arctic tundra ecosystem. However, the impact of fox predation depended on the location and timing of incubation of the nest, demonstrating the importance of incorporating time into the ‘landscape of fear’ concept.

Doubly robust criterion for causal inference
Canadian Journal of Statistics, Volume 53, Issue 3, September 2025.Abstract In causal inference, semiparametric estimation using propensity scores has rapidly developed in various directions. At the same time, although model selection is indispensable in statistical analysis, an information criterion for selecting the regression structure between the potential outcome and explanatory variables has not been well ...

Noisy matrix completion for longitudinal data with subject‐ and time‐specific covariates
Canadian Journal of Statistics, Volume 53, Issue 3, September 2025.Abstract In this article, we consider the imputation of missing responses in a longitudinal dataset via matrix completion. We propose a fixed‐effect, longitudinal, low‐rank model that incorporates both subject‐specific and time‐specific covariates. To solve the optimization problem, a two‐step optimization algorithm is proposed, which provides good ...
