Detecting departures from the conditional independence assumption in diagnostic latent class models: A simulation study

2024-08-13

Abstract excerpt

<title>Abstract</title> <p><bold>Background</bold> Latent class models can be used to estimate diagnostic accuracy without a gold standard test. Early studies often assumed independence between tests given the true disease state, however this can lead to biased estimates when there are inter-test dependencies. Residual correlation plots and chi-squared statistics have been commonly utilized to assess the validity...
