• Best approach and alternative to simple logistic regression to model the probability of belonging to a group

  Hello  I need a little help on picking the right approach to solve my pronlem. I have a continuous variable X than can take any value between [-45 0].I have a dataset of X values for 12 distinct groups, see below their histogram. I'm trying to build two models:1) A model that, for a given new value of X gives me the probability of belonging to each goup and gives me the most likely group.2) A mode...

• how to use jsl to calculate standard deviation by ID

  Hi, I have a table similar to this, and I wanted to select IDs where there are more than one entry and calculate standard deviation of the result grouped by ID. For example, in this case, I need to select ID 12345 and calculate standard deviation of the first 3 results.  I know I can do this by tabulate, but my actual table is very big, more than 1 million rows, tabulate by ID and calculate standa...

I would like to retain the thick lines if possible, the data in these columns is currently labeled as Character - Ordinal. I was able to merge axes as numerical columns however this loses the thick lines. Is there any solution to this? Any help is g...

• Frequency=0 in Life Distribution Platform in Reliability Analysis

  I have a reliability dataset where some of the readouts did not have any fails. Do I merge these readouts with the ones that have fails or include them separately? Please refer to Setup1 Vs Setup2 in the snippet below [JMP file attached too]. Weibull alpha and beta parameters between Setup1 and Setup2 are drastically different. To me, setup2 seems reasonable since it includes complete information....

• How to reduce the number of runs in design?

  Dear sir/madam, In JMP17 I have made a design starting from 8 2-level factors, of which 5 are hard-to-change. For the hard-to-change factors only main effects are considered, for the easy-to-change factors 2nd order interactions are also evaluated.Using Custom Design, 32 runs were generated, consisting of 8 whole plots.Now, every run represents an adhesive formulation I would like to test on a ser...
