%description
Implementation of the three-step approach of latent transition cognitive
diagnosis model (CDM) with covariates. This approach can be used to assess
changes in attribute mastery status and to evaluate the covariate effects
on both the initial states and transition probabilities over time using
latent logistic regression. Because stepwise approaches often yield biased
estimates, correction for classification error probabilities (CEPs) is
considered in this approach. The three-step approach for latent transition
CDM with covariates involves the following steps: (1) fitting a CDM to the
response data without covariates at each time point separately, (2)
assigning examinees to latent states at each time point and computing the
associated CEPs, and (3) estimating the latent transition CDM with the
known CEPs and computing the regression coefficients. The method was
proposed in Liang et al. (2023) <doi:10.3102/10769986231163320> and
demonstrated using mental health data in Liang et al. (in press; annotated
R code and data utilized in this example are available in Mendeley data)
<doi:10.17632/kpjp3gnwbt.1>.
