• Dunnett's for Multiple Ys

  I am trying to get a script that will run Dunnett's on multiple Ys automatically in fit model, my issues:   If I change the multiple comparisons part where the factor and level is not a variable it works but only for the first Y, it will not repeat the Dunnett's part for the remaining Ys.   So my questions:   1.  Why doesn't this work like the fit model with a variable being used for the factor an...

  Hi - Is it possible to use a script or other approach to automate validation testing of my multiple regression model?  Currently, I am manually removing a subset of rows from my original model, using the balance of rows for regression, and then using the subset to evaluate how well the model performed.  I then repeat this numerous times.  It is very time consuming, especially given the fact that I...

• Regression Covariables

  Quick question. I am using a Cox regression model and was wondering if I could include variables that are dependent upon each other in the same model. For example, would adding height, weight, and BMI as covariables affect the model, given that BMI is directly dependent upon height and weight? Another example, in transplant studies I want to know how gender affects survival. So I use both recipien...

• Cox Regression variable selection

  Hello everyone, is there a way to select variables for Cox regression using a stepwise model in JMP? The stepwise regression model from the Fit Model only has a "Y" category, whereas for Cox-regression I would imagine that in order to choose the best variables I would need an option to add both a "Y" category (event), as well as an "X" category (Time to event)? If not would I put the event in for ...
