• Save Inverse Prediction Formula

  For some reason the command "Save Inverse Prediction Formula", does not save the formula to the associated table. The command "Custom Inverse Prediction" works and does calculate one of the two possible X variable solutions (the function is a Gaussian curve and therefor has two X solutions for each Y variable). But I can not seem to get the formula to save as a new column.
  
  I have read the docs on ...

• invalid matrix token

  Can someone tell me what the error "invalid matrix token" means? I am using the following script in a for loop (j as iterator) in order to graph and add a box for limits. However, the script is giving me the matrix error. Can someone give me a hint?

• missing data in calculated formula

  I am writing a script that asks JMP to create a new column in my data table, then populate that column with the sum of the values of 25 existing columns. It works fine, except that if there is missing data in any of the 25 columns, the total displays as 0 (zero), when it should display as missing. It won't work to tell JMP that 0 is not a valid value, because in some cases each of the 25 columns...

• How to Express Tabulate results as percentages of row totals

  Hi,
  
  I am using Tabulate to summarise raw categorical data table. This works well but I would like the results expressed as percentages of row totals.
  The raw table format is columns with Date, Failure Mode ("OK", "Chips", "Flakes" etc). Result should be a row for each day and a column for each failure mode, so each row contains % "OK", % "Chips", % "Flakes" for each day.
  
  Thanks,

• use a polynomial fit equation to predict new data

  I need to create a new column that uses a calculated "Polynomial Fit Degree=4" equation to predict a value.
  
  I have 97 different sites with monthly average temperature data. Therefor 97 different figures with a satisfactory line drawn through the 12 data points. Here is an example of one site's equation:
  
  T_AVE = 2.127629 + 0.0769089*DOY - 0.0015991*(DOY-183.083)^2 - 2.3911e-6*(DOY-183.083)^3 + 2.145...
