Yao, Lili; Haberman, Shelby; McCaffrey, Daniel F.; Lockwood, J. R. – ETS Research Report Series, 2020
Minimum discriminant information adjustment (MDIA), an approach to weighting samples to conform to known population information, provides a generalization of raking and poststratification. In the case of simple random sampling with replacement with uniform sampling weights, large-sample properties are available for MDIA estimates of population…

Martínez, Sergio; Rueda, Maria; Arcos, Antonio; Martínez, Helena – Sociological Methods & Research, 2020
This article discusses the estimation of a population proportion, using the auxiliary information available, which is incorporated into the estimation procedure by a probit model fit. Three probit regression estimators are considered, using model-based and model-assisted approaches. The theoretical properties of the proposed estimators are derived…

Levine, Burton; Berzofsky, Marcus E.; Hampton, Joel; Battles, Haven B. – International Journal of Social Research Methodology, 2019
Dual-frame, random-digit-dialing (DFRDD) surveys, using a frame of landline telephone numbers and a frame of cell phone numbers, have become the norm for telephone surveys. Two alternative frame constructions sample exclusively from a cell phone frame, referred to as the 'single-frame cell,' and sample from the listed landline frame and the cell…

Brick, J. Michael; Andrews, William R.; Mathiowetz, Nancy A. – Field Methods, 2016
Although using random digit dialing (RDD) telephone samples was the preferred method for conducting surveys of households for many years, declining response and coverage rates have led researchers to explore alternative approaches. The use of address-based sampling (ABS) has been examined for sampling the general population and subgroups, most…

Mann, Heather M.; Rutstein, Daisy W.; Hancock, Gregory R. – Educational and Psychological Measurement, 2009
Multisample measured variable path analysis is used to test whether causal/structural relations among measured variables differ across populations. Several invariance testing approaches are available for assessing cross-group equality of such relations, but the associated test statistics may vary considerably across methods. This study is a…

Rijmen, Frank; Manalo, Jonathan R.; von Davier, Alina A. – Applied Psychological Measurement, 2009
This article describes two methods for obtaining the standard errors of two commonly used population invariance measures of equating functions: the root mean square difference of the subpopulation equating functions from the overall equating function and the root expected mean square difference. The delta method relies on an analytical…

Rosen, Russell S. – International Journal of Special Education, 2009
This is a critical review of surveys conducted on the American deaf population since 1990. There is no agreement among the surveys on the number of deaf and hard of hearing individuals in the US. This behooves us to study the question: Why the lack of agreement in estimates and prevalence rates of the American general deaf and the deaf child…

Van Swol, Lyn M.; Seinfeld, Emily – Human Communication Research, 2006
This article integrates research on minority influence and information sampling in groups. The traditional information-sampling paradigm implies that the discussion bias for common over unique information affects all types of groups universally. We proposed an alternative in which information sampling depends on the composition of opinions. We…

Leech, Nancy L.; Kees, Nathalie L. – Journal of Counseling and Development, 2005
There is not a "typical" women's group, nor are there "typical" women's issues. Every women's group is diverse, with as many viewpoints and perspectives as there are members in the group. Using the group format for women is common practice with many counselors. It is interesting that there has been little empirical research reported on women's…
