A Study on the Class of Chain Ratio–type Estimators

 This paper considers the problem of estimating the population mean Ybar of the study variate Y using information on different parameters such as population mean $(bar{X})$, coefficient of variation $(C_x)$, kurtosis  $beta_{2(x)}$, standard deviation $(S_x)$ of the auxiliary variate x and on the correlation coefficient, $rho$, between the study variate $Y$ and the auxiliary variate $...

Latent class CUB models

The paper proposes a latent class version of CUB models for ordinal data to account for unobserved heterogeneity. The extension, called LC-CUB, is useful when the heterogeneity is originated by clusters of respondents not identified by covariates: this may generate a multimodal response distribution, which cannot be adequately described by a standard CUB model. The LC-CUBmodel is a finite mixtu...

Simple Estimators for the Simple Latent Class Mastery Testing Model

Latent class models for mastery testing differ from continuum models in that they do not postulate a latent mastery continuum but conceive mastery and nonmastery as two latent classes each characterized by different probabilities of success for the test items. Several authors, including Emrick and Adams (1969), Besel (1973), Davis, Hickman, and Novick (1973), and Macready and Dayton (1977), giv...
