• Date formula not working

  What could cause the Date function to not fill the column. I have three tables, one of which the Date Time : Date (MDY) worked just fine. In the other two tables however, after selecting the proper table columns (MONTH, DAY, YEAR), no date data filled the column. This seems so simple that I am rather perplexed. Ideas?

• How to calculate 'slope' or gradient

  I am looking for a way to calculate the slope or gradient of data. I need to do the same function as slope (X1:X4, Y1:Y4) in excel but to be able to program it into a jmp script.

• DOE analysis in JMP, ocnfused

  I used DOE ----> Screening Design to set up a DOE study for 1out put (height, maximize purpose) with 3 factors (rate, temp, speed, all continuous). I chose the design of full factorial (8 runs + 2 center points).
  
  After I got the results of the totally 10 runs, I type them into the design table.
  
  Here, I got confusion.
  
  Now I have two ways to analyze the data.
  
  1. Analyze ---> Fit Model.

• Need some help on testing some assumptions and validating data

  I was hoping that someone might be able to help me accomplish the following tasks in JMP. I'm kind of new to the software.
  
  I need to test:
  1) Dependent dichotomous? Independent variables metric or dichotomous?
  2) Ordinal independent variable included in analysis?
  
  There is some more, but I'll just throw this out there and see if anyone can help out.
  
  Thanks

• Least squares regression - removing insignificant terms quickly?

  Hi all-
  
  I am doing least squares fits, up to cubic with 15 X's. Only the 1st several ever turn out "significant", so those at the "bottom" with small p values could be removed...one at a time...as long as R^2 doesn't go down. This would be a slow iterative process, but would result in a much shorter equation. I know of one other tool that will do this.
  
  Can JMP?
  
  Thanks,
  Dave
