Although multiple-response questions are quite common in survey research, Stata's official release does not provide much capability for an effective analysis of multiple-response variables. For example, in a study on drug addiction an interview question might be, "Which substances did you consume du...
The purpose of this paper is to briefly introduce two most common applications of multiple group item response theory (IRT) models, namely detecting differential item functioning (DIF) analysis and nonequivalent group score linking with a simultaneous calibration. We illustrate how to conduct those ...
In addition, if more than one comparison form was analyzed for a given outcome (e.g., dose–response analysis; highest vs. lowest), all comparison forms were included in our study. Data extraction and analysis For every eligible systematic review with meta-analyses, we extracted the first ...
These can also be computed for each response variable or for each outcome of an ordinal or a categorical variable. margins now automatically performs the requested marginal analysis for all variables and all outcomes. You can, of course, still request that it produce the analysis for only a ...
Multiple imputation of missing blood pressure covariates in survival analysis This paper studies a non-response problem in survival analysis where the occurrence of missing data in the risk factor is related to mortality. In a study ... S. van Buuren,HC Boshuizen,DL Knook 被引量: 3817发表: ...

Lastly, the HBSC-SCL is well-validated in the general population and the present age-group. Limitations Some limitations must be kept in mind when interpreting the results. First, at an instrument level, we sought to maintain comparability with the original HBSC-SCL by collapsing two response ca...
