I'd like to help with your question but want to get some background information first. I assume you are trying to satisfy the requirement of normality of errors in your regression model?
How are you determining that your…"
Thanks for reading the e-book and the question. First off the Intelligent Response Attribution solution will keep track of campaigns that are delivered and then a customers action after the delivery. So if multiple emails are…"
"I thought the 10 month program at NC State was sufficient but it depends on your background and aptitude for an analyst or data scientist role. It was enough for me to learn and become very proficient in SAS and start learning R and a few…"
"Hey guys, this is a great discussion on a topic I haven't seen discussed too often. First off the big difference I have seen between MMM and Response Attribution is the granularity of the data you have to work with. I recently…"
If you are performing simple linear regression I would examine the residuals of the model output. From there you can determine if you need to add higher order terms or need to transform the independent variable. If you plot…"
"This is what I have done in the past to get the Youden Index from proc logistic in SAS. After your model statement use this code:
(your code may look slightly different. outroc outputs the specificity and sensitivity)
"I usually go straight to putting the scores from regression into deciles and see if I get an even distribution in each decile. I also look to see how many "successes" I get in each decile and how those are distributed from the top…"
"I generally don't find a need to plot the ROC curve, I just care about the c-statistic or area under the curve. Are you asking how you find the Youden Index (cutoff value) from logistic regression in SAS?"
I am a graduate of the 2011 NC State Analytics program so I can speak about my experience in and out of the program. Before entering the program I graduated with a masters in Applied Mathematics focusing mainly on numerical techniques…"
