Basics Concepts of Statistical Power
Statistical power is the probability that a statistical test will show a result to be significant if it is. In designing studies power calculations are useful to determine necessary sample size for an effective study. The presentation will briefly cover the conceptual basis of power, SAS PROC POWER, and a marketing example.
Basic Concepts of Logistic Regression
Logistic regression is a type of regression analysis often used to predict a dichotomous outcome based on multiple predictors. Logistic regression assigns a predicted probability for a case belonging to the outcome of interest. This brief presentation will cover the use of logistic regression, SAS PROC LOGISTIC, and a marketing example.
