WebThe facts. The fecal immunochemical test (FIT), also called an immunochemical fecal occult blood test (iFOBT), is a newer kind of stool test that also detects occult (hidden) blood in the stool. This detection is important because it can be a sign of precancerous polyps or colorectal cancer. Blood vessels at the surface of larger polyps or ... WebAug 1, 2024 · The standard procedure for conducting LCA is to run a sequence of cousin models, starting with a one-class model, and then adding one class at a time [4].One then compares these models using statistical and substantive criteria, to identify the best model (Table 1).A popular indicator of model fit is the Bayesian Information Criterion (BIC) [6, 19].
