SAS is general-purpose software with a wide variety of approaches for statistical analyses. One of its best features, Logistics regression, is widely used now a days in marketing research, finance and clinical studies when the dependent variable is dichotomous. However, ordinary linear regression was routinely used before we had the modern statistical packages for analyzing […]

Binary Logistic Regression Using SAS We begin by presenting an example that will be utilized to show the analysis of binary information. We then talk about the stochastic structure of the information in regards to the Bernoulli and binomial circulations, and the methodical structure in regards to the logit change. The outcome is a generalized […]

Just like a linear regression, once a logistic (or any other generalized linear) model is fitted to the data it is essential to check that the assumed model is actually a valid model. A thorough examination of the extent to which the fitted model provides an appropriate description of the observed data, is a vital […]
