A Discrimination Theory Based on Categorical Variables and Its Application to Meterological Problems
Although the methodology for handling ordinal and dichotomous observed variables in structural equation models (SEMs) is developing rapidly, several important issues are unresolved. One of these is the optimal test statistic to apply as a test of overall model fit. We propose a new ‘‘vanishing tetrad’’ test statistic for such models. We build on Bollen’s (1990) simultaneous test statistic for t...

We collected epidemiological and clinical data in addition to scoring systems commonly used in critical care units and those more specific to cirrhotic patients.
