![]() TOPNOTCH Frequency Percent Frequency PercentĪDMIT Frequency Percent Frequency Percent Proc freq data = probit table topnotch admit run The FREQ Procedure Outcome variable must be coded with zeros and ones, so we will include aįrequency of our outcome variable admit to check this. The probit model does so using the cumulative distributionįirst, let us examine the dataset and our response variable. Thus, our model will calculate a predicted probability of admissionīased on our predictors. Our outcome variable is binary, and we will use a probit Using undergraduate GPA, GRE scores, and the reputation of the school of the Using this dataset ( ), we can predict admission to graduate school Students’ GRE score, and whether or not the student was admitted to graduate Reputation of the school of the undergraduate (a topnotch indicator), the Undergraduates applying to graduate school and includes undergraduate GPAs, the ![]() The data in this example were gathered on This page shows an example of probit regression analysis with footnotesĮxplaining the output in SAS.
