https://communities.sas.com/t5/Statistical-Procedures/Logistic-regression-Accuracy-rate-of-prediction/m-p/837405#M41471 <P>I am doing a project using logistic regression to predict an outcome. Before conducting the analysis, I split the data into train and test (70-30 ratio). I used sas enterprise guide for the analysis. I have gotten my result, and I have a question. How can I get the accuracy rate for the prediction of the test data?&nbsp;</P> Fri, 07 Oct 2022 14:02:37 GMT Winnifredik 2022-10-07T14:02:37Z https://communities.sas.com/t5/Statistical-Procedures/Logistic-regression-Accuracy-rate-of-prediction/m-p/837405#M41471 <P>I am doing a project using logistic regression to predict an outcome.

See in particular the use of the FITSTAT option in the SCORE statement which provides a table of various statistics. The simple Error Rate for the two data sets compares the proportions of incorrectly classified observations in each data set. For details on the statistics, see "Model Fitting Information" in the Details section of the LOGISTIC documentation.</P> Fri, 07 Oct 2022 15:21:15 GMT https://communities.sas.com/t5/Statistical-Procedures/Logistic-regression-Accuracy-rate-of-prediction/m-p/837424#M41472 StatDave 2022-10-07T15:21:15Z
