Using Multivariate Statistics

The R package mice imputes incomplete multivariate data by chained equations. The software mice 1.0 appeared in the year 2000 as an S-PLUS library, and in 2001 as an R package. mice 1.0 introduced predictor selection, passive imputation and automatic pooling. This article documents mice, which extends the functionality of mice 1.0 in several ways. In mice, the analysis of imputed data is made completely general, whereas the range of models under which pooling works is substantially extended. mice adds new functionality for imputing multilevel data, automatic predictor selection, data handling, post-processing imputed values, specialized pooling routines, model selection tools, and diagnostic graphs. Imputation of categorical data is improved in order to bypass problems caused by perfect prediction. Special attention is paid to transformations, sum scores, indices and interactions using passive imputation, and to the proper setup of the predictor matrix. mice can be downloaded from the Comprehensive R Archive Network. This article provides a hands-on, stepwise approach to solve applied incomplete data problems.

According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

Multiple Imputation for Nonresponse in Surveys

Statistical Analysis with Missing Data

Nonresponse is a threat to the validity of conclusions based on survey data. In general, two strategies are used to counteract this threat. The first strategy is to reduce the proportion of nonresponse as far as possible, the second is to statistically adjust for the remaining nonresponse. Interview surveys are still the norm for official statistics, social studies und market research in the Netherlandr, und interviewers are an important factor in the battle against nonresponse. We focus on interviewers' opinions on nonresponse und their attitudes regarding the role of the interviewer in persuading potential respondents. In a special project at Statistics Netherlands the continuous survey on living conditions (POLS) was redesigned. During that study interviewer data were collected. It is shown that interviewer attitude und response rate are correlated. Interviewers with a positive attitude towards persuasion strategies attain a higher response rate. No dlferences between interviewers are found regarding self-reported 'door step' behaviour.

Operationalization and research strategy

This article describes a technique to analyze randomized response data using available structural equation modeling (SEM) software. The randomized response technique was developed to obtain estimates that are more valid when studying sensitive topics. The basic feature of all randomized response methods is that the data are deliberately contaminated with error. This makes it difficult to relate randomized responses to explanatory variables. In this tutorial, we present an approach to this problem, in which the analysis of randomized response data is viewed as a latent class problem, with different latent classes for the random and the truthful responses. To illustrate this technique, an example is presented using the program Mplus.

Because variables may be correlated in the social and behavioral sciences, multicollinearity might be problematic. This study investigates the effect of collinearity manipulated in within and between levels of a two-level confirmatory factor analysis by Monte Carlo simulation. Furthermore, the influence of the size of the intraclass correlation coefficient (ICC) and estimation method; maximum likelihood estimation with robust chi-squares and standard errors and Bayesian estimation, on the convergence rate are investigated. The other variables of interest were rate of inadmissible solutions and the relative parameter and standard error bias on the between level. The results showed that inadmissible solutions were obtained when there was between level collinearity and the estimation method was maximum likelihood. In the within level multicollinearity condition, all of the solutions were admissible but the bias values were higher compared with the between level collinearity condition. Bayesian estimation appeared to be robust in obtaining admissible parameters but the relative bias was higher than for maximum likelihood estimation. Finally, as expected, high ICC produced less biased results compared to medium ICC conditions.

Social and behavioral research often involves problems and data that are viewed as a hierarchical system, with individuals and groups defined at separate levels of this hierarchical system. Standard multivariate models are not appropriate for the analysis of such hierarchical systems, even if the analysis includes only variables at the lowest (individual) level, because the standard assumption of independent and identically distributed observations is generally not valid. The consequences of using uni-level analysis methods on multilevel data are well known: the parameter estimates are unbiased but inefficient, and the standard errors are negatively biased, which results in spuriously ‘significant’ effects (cf. Snijders and Bosker, 1999; Hox, 2002). Multilevel analysis techniques for the linear multiple regression model are well developed and the required software is widely available (Raudenbush and Bryk, 2002; Goldstein, 1995).
