Hi!
Title should read Which test should I use? Binary Y, continuous X

First time poster - been working in quality for the last 4 years or so in a service environment so my Lean Six Sigma training and certification hasn't focused much on statistical analysis at all. I'm trying to read as much as I can and Minitab is helping me in the process become familiar with the options available.

One situation that arises very often in my business is we try and find out whether speeding up a process results in customers being more likely to purchase from us. Essentially we have a continuous X, the TAT, and a binary response Y which is accept or not accept business. This is the foundation for many improvement projects that we work on and that I coach.

I started looking into using binary logistic regression however received an error. * ERROR * = and arguments needed.

My data is simply C1 contains the Y response (won/loss), and C2 the X TAT. In the test window I select C1 as the response and C2 as the factor

If it helps my continuous data is non-normal

A couple of questions:
1. Am I using the right test?
2. Is there any reason I would be receiving an error from Minitab?

Thanks!

Re: Which test should I use? Binary Y, Continuous Y

It sounds like you are using the correct test. There error is most likely due to how the test was specified, or how the data were entered. If you attach that data, we can help.
