The Independence of Irrelevant Alternatives assumption inherent in multinomial logit models is most frequently … Web5 jan. 2024 · Trend tests between the ordinal covariate and the effect size may be conducted by testing whether the slope of the regression line is equal to zero against a two-sided alternative. Typically, the procedure utilizes unweighted regression, which ignores variability in estimation of the effect size.

By means of t-test you are assessing whether there is a significant difference between two sets of data --- e.g. the realizations of two random variables X and Y. When using t-test you are doing a hypothesis test, and you can't control for any variable. To be more specific, when doing hypothesis tests you are not establishing any causal ...
