SAS A00-240 Exam - Topic 9 Question 22 Discussion

One common approach for predicting rare events in the LOGISTIC procedure is to build a model that disproportionately over-re presents those cases with an event occurring (e.g. a 50-50 event/non-event split).What problem does this present?
B) Only the intercept estimate is biased.
A) All parameter estimates are biased.
C) Only the non-intercept parameter estimates are biased.
D) Sensitivity estimates are biased.

Not sure about this, can we really trust those estimates?

D makes sense too, sensitivity can get messed up.

Wait, only the intercept? That seems off.

A is the right answer, all estimates get skewed.

I’m leaning towards the idea that sensitivity estimates could be biased too, especially if the model is skewed.

I feel like I read somewhere that only the non-intercept estimates could be biased, but I can't recall the details.

I think we practiced a similar question where we talked about how the intercept might be affected more than other estimates.

I remember discussing how oversampling can lead to biased parameter estimates, but I'm not sure if it's all parameters or just some.

Hmm, this one seems tricky. I'll need to carefully review the options and think through the possible configurations for clientless SSLVPN.

Okay, I think I've got this. Based on the requirements, I'd say we need to apply the Data Format Transformation, Data Model Transformation, and Event-Driven Messaging patterns in addition to the Orchestration compound pattern. The other options don't seem as directly relevant.
