UvA - DARE ( Digital Academic Repository ) Planned missing designs to optimize the efficiency of latent growth parameter estimates
We examine the performance of planned missing (PM) designs for correlated latent growth curve models. Using simulated data from a model where latent growth curves are fitted to two constructs over five time points, we apply three kinds of planned missingness. The first is item-level planned missingness using a 3-form design at each wave such that 25% of data are missing. The second is wave-miss...
متن کاملOn the joys of missing data.
We provide conceptual introductions to missingness mechanisms--missing completely at random, missing at random, and missing not at random--and state-of-the-art methods of handling missing data--full-information maximum likelihood and multiple imputation--followed by a discussion of planned missing designs: Multiform questionnaire protocols, 2-method measurement models, and wave-missing longitud...
متن کاملTowards a Cautious Modelling of Missing Data in Small Area Estimation
In official statistics, the problem of sampling error is rushed to extremes when not only results on sub-population level are required, which is the focus of Small Area Estimation (SAE), but also missing data arise. When the nonresponse is wrongly assumed to occur at random, the situation becomes even more dramatic, since this potentially leads to a substantial bias. Even though there are some ...
متن کاملThe Effect of Education Based on the Theory of Planned Behavior on expression of Preventive Behaviors concerned with Brucellosis in Farmers
Background & Aim: Brucellosis is one of the most common animal-to-human transmissible diseases and one of the major health problems worldwide, especially in developing countries. The purpose of this study was to determine the effect of education based on Theory of Planned Behavior on preventive behaviors concerning with brucellosis in farmers. Methods: This research is a quasi-experimental stu...
متن کاملTwo-Phase Sampling and Weighting
Non-response or other missingness may be occurred in various forms. In this paper, we consider unit non-response, and hence make attempts for adjustments by appropriate weighting. Our special exercise is concerned a two-phase sampling case so that, first, a large sample survey has been conducted with a rather general questionnaire. In the end of this face-to-face contact the interviewer has ask...
