• What is the role of "Freq" in the Partition decision tree model?

  Please consult the experts: Are there any examples of how "Freq" plays a role in the decision tree model of "Partition"? I searched for the script and couldn't find it. Thanks!

• Standard betas for logistic regression

  I would like to compare strength of effect in my logistic regression model.  In least squares models I can bring up and compare standardized beta coefficients.  Can this be done with logistic models?  (I don't see the option in "columns" option).  Or, is there another method to compare the strength of effect of each of my terms in the model? ThanksFishguy

The goal is to detect which variables influence the response and find the optimal settings of these variables. Because of the small number of observations I decided to divide data into only two categories, training and test data set (omitting the validation data set). My strategy is to apply...

• How do use JSL to quickly compare two sets of range columns in order to get the minimum of each column?

  The title is a bit hard to understand. Take this big class as an example:
  1. First, summarize the average values of "height" and "weight" by age.
  2. Then summarize the median of "height" and "weight" by age.
  3. Then compare the mean and median of "height" and take their minimum.
  Finally, compare the mean and median of "body weight" and take their minimum. I'll use the following code and finally loop t...
