Decision Tree Question

Scott Carl
Hello,

In looking into the tree procedure, I see where we can control for minimum
cases within each node using the growthlimit subcommand. I am looking for
minimum respondents within each node, rather than minimum cases. Does
anyone know how to accomplish this? Thanks in advance.

I'm not sure I understand the distinction in this context. What is the difference between a "case" and a "respondent" in your data?

Re: Decision Tree Question

A case is a row of data, and respondents are just those that responded to
the event. In the data I am looking at here, we have about a 2% response
rate, so 2 in 100 cases are flagged as having responded.

It looks like the tree procedure can control for minimum row cardinality,
but I am looking to control for minimum response count.

Thanks in advance.
