Problems with using ordinal variables. Regression Analysis Multiple Logistic Regression Use a Multiple Logistic Regression when you want to predict a qualitative dependent variable, such as the presence or absence of a disease, from observations of one or more independent variables, by fitting a logistic function to the data. While linear regression can have infinite possible values, logistic regression has definite outcomes. While the outcome variable, size of soda, is obviously ordered, the difference between the various sizes is not consistent. Where the ordinal logistic regression begins to depart from the others in terms of interpretation is when you look to the individual predictors. NOTE: This page is under construction!!

Ordinal logistic regression (henceforth, OLS) is used to determine the relationship between a set of predictors and an ordered factor dependent variable. Ordinal logistic regression is used when the dependent variable (Y) is ordered (i.e., ordinal). The crucial limitation of linear regression is that it cannot deal with DV’s that are dichotomous and categorical Logistic regression employs binomial probability theory in which there are only two values to predict: that probability (p) is 1 rather than 0, i.e. None of the cells is too small or empty (has no cases), so … There are three main types of logistic regression: binomial: target variable can have only 2 possible types: “0” or “1” which may represent “win” vs “loss”, “pass” vs “fail”, “dead” vs “alive”, etc. Title: Factorial Analysis of Variance Author: Katlyn Moran Last modified by: reviewer Created Date: 9/19/2002 7:22:30 PM Document presentation format.
