Latent Regression in Rasch Framework
Rasch-type measurement models are an important and widespread instrument in estimating latent variables. In this contribution the attention is set on a special type of Rasch models: the latent regression Rasch models. The interest is focused on two main problems: the latent regression modelling of longitudinal data and latent regression modelling with missing not at random responses. The empirical study concerns the measurement of Health related Quality of Life in cancer patients.
