M. Vissers replied to Jim Parker's discussion Clustering responses to define dependent variable for logistic regression in the group Analytical Techniques

"Perhaps you should calculate Cronbach's alpha to check whether the 5 questions do measure the same construct. If not, try to find out which questions do measure the construct you're interested in. If you have determined the correct…"

Ralph Winters replied to Jim Parker's discussion Clustering responses to define dependent variable for logistic regression in the group Analytical Techniques

"Do you know what the "certain behavior" is? Then set it up as a regression problem. If not, I would look into performing a root cause analysis to see what the true drivers are that are leading to the latent response. Sometimes, that…"

Jim Parker replied to Jim Parker's discussion Clustering responses to define dependent variable for logistic regression in the group Analytical Techniques

"Thanks for your response. My concern with using any of these methods stems from the fact that I am presently just trying to define people with a propensity to have a certain behavior. All of these questions address aspects of that…"

Ralph Winters replied to Jim Parker's discussion Clustering responses to define dependent variable for logistic regression in the group Analytical Techniques

"I would have chosen factor analysis instead of cluster analysis. With cluster analysis your variables can still all be in the same cluster and be correlated with each other. Factor analysis will remove the correlation. However, the…"

Clustering responses to define dependent variable for logistic regression

Some colleagues of mine are working with survey responses, and are attempting to predict behaviors with demographic data. So, the plan is to define a dependent variable from some combination of responses to the survey questions, and then use a regression technique to model this dependent variable using other characteristics of the respondents. We all agree on the 5 or so questions that will define the dependent variable, but we disagree on how to specify the definition.I want to look at the…See More
