SAS A00-240 Exam - Topic 4 Question 5 Discussion

Actual exam question for SAS's A00-240 exam

Question #: 5
Topic #: 4

This question will ask you to provide missing code segments.

A logistic regression model was fit on a data set where 40% of the outcomes were events (TARGET=1) and 60% were non-events (TARGET=0). The analyst knows that the population where the model will be deployed has 5% events and 95% non-events. The analyst also knows that the company's profit margin for correctly targeted events is nine times higher than the company's loss for incorrectly targeted non-event.

Given the following SAS program:

What X and Y values should be added to the program to correctly score the data?

AX=40, Y=10

BX=.05, Y=10

CX=.05, Y=.40

DX=.10, Y=05

Wait, how can the profit margin be nine times higher? That seems off.

Not sure about that, isn’t Y supposed to reflect the profit margin?

I think Y should definitely be 10, makes sense!

X should be 0.05 for the new population.

I vaguely recall that the values should align with the profit-loss ratio, but I’m torn between options B and C. I need to think this through more.

This question feels similar to one we practiced where we had to adjust for class imbalance. I think X should be 0.05, but I’m not confident about Y.

I’m not entirely sure, but I think Y should represent the profit margin, which is nine times the loss. That might help in determining the right values.

I remember we discussed the importance of adjusting for the population distribution, so I think X should reflect the 5% events.

Hmm, I'm a bit unsure about this one. Is it possible the customer could also want to prevent other types of outbound transactions, like Miscellaneous Issue? I'll need to think this through carefully.

Hmm, I'm a bit unsure about this one. I know EPM Workspace has some administration tools, but I can't recall all of them off the top of my head. I'll have to think this through step-by-step.

This looks like a straightforward question on the performance advantages of optimistic vs. pessimistic concurrency control. I think I can handle this one.

Option B about looping and branching doesn't sound right to me. I think the critical path is a linear sequence of tasks.
