SAS Statistical Business Analysis SAS9: Regression and Model Exam

Model selection questions were tough but NerdExam prepped me well.

The A00-240 covers a lot of ground - linear regression, logistic regression, ANOVA, model diagnostics, and more. I focused extra time on interaction effects and ROC curve interpretation using these questions. Passed last week and already applying the skills at work.

Still working through the logistic regression and categorical data sections but these questions are solid prep for what A00-240 actually covers.

Coming from Excel-based reporting, the regression diagnostics section was a real eye-opener. These questions helped me build intuition for multicollinearity before exam day.

Used PROC REG for years but variable selection and model assessment still tripped me up. These questions helped me nail the stepwise selection concepts before sitting A00-240.

Some questions here felt more straightforward than what I saw on the actual A00-240, especially around PROC GLM. But the explanations for model assessment and ROC curves were genuinely useful - worth it for anyone preparing for this certification.
