  • Formula for Weibull distribution with a co-variate

    Hello,I performed a survival analysis with censored data, and a co-variate called "AGE". I used "Save Probabilty Formula" to save the formula in the data table. Now when  I right click the newly created column, and click on "Formula", I get the below formula.  My question is could someone advise on the actual formula for Weibull Distribution where I can substitute the calibrated co-efficients, and...

    Hello,I would like to simply insert a newline character at the end of each item in an array, being written to file.  Does JMP not recognize '\n'?  If so how would I get it to outputfile1file2file3rather thanfile1\nfile2\nfile3for(i=1,i<=length(Files),i++, filestring=filestring|| " " || char(Files[i]) || "\n"); f=Save Text File(pypath || "argfile.txt",filestring,mode("replace"));Thanks!

  • Subsetting a datatable with a For loop and performing colunm operations in each subset

    Dear community, i have a hard time on this topic may be someone can help. My Datatable comprises many parts under "Serialnumber" that are measured at different point of time "Timestamp". The results of the Measurement (like Isc, Pmpp, ...) ist stored in rows with increasing measurement time. What i need to do ist to normalize the measurement value with the very first measurement (earliest in time)...

  • Analyzing texts

    So far I have been using JMP for my statistical calculations in the research, and I have been stuck using different windows-programs for my qualitative research. I wonder if I could use JMP for that too? I have two specific questions concerning text analysis with JMP that I have not found the answer to:1) is it posible to use JMP for qualitative analysis? i.e. to code the texts in several steps, d...

  • JSL won't set column Format

    Hi all,I'm trying to copy the column names, data types, modeling types and formats from one table into a new one, but when I try to set the column format, it never takes and just reverts to "Best". I've been banging my head against this for a while and am completely stumped why it's not working. Below is my code and the resulting output that shows the column format is valid but just doesn't stick....

  • Simulating data to generate larger data set for building models

    Dear JMP community,   I'm trying to work out a way to generate simulated data to better train a model I'm building.   I have a decent sized data set -- a few thousand data points, but would like to generate simulated data that maintains a similar structure as the original data in order to improve upon the model. I'd like to have somewhere around 20K-50K data points with a similar structure in orde...

  • Writing a data table in Python

    I perform extensive post-processing in Python and then move that data to jmp for analysis. Is the data table format standardized or documented somehow so that I can write jmp files directly? Right now I am writing to an intermediate CSV and then importing which is just another step to go wrong. The answer to a similar question from last year suggested that the user write their data to a JSL script...

  • Selecting Number of Clusters in Hierarchical Clustering

    One way to select possible number of clusters in hierarchical methods is to identify the relatively large changes in distance as number of clusters change (see table below). When I look at the actual distance measure from the table (clustering history below dendogram), there is a bigger jump from 3 clusters to 4 than from 4 to 5 (smaller), suggesting 4 may be the right decision. However, when you ...

  • Beta Generalized Regression and adjusted chi-square values

    I have a data set from a two-choice rodent feeding trial. We were testing the effectiveness of 10 deterrents by coating them on seeds and offering them to rodents alongside control seeds that were uncoated. The explanatory variable is which of the 10 deterrents the treatment seed was coated with, and the response variable is the proportion of control seed and treatment seed consumed.  The question...

  • DF Dens for repeated measures ANOVAs

    Dear JMP Community, When I run repeated measures ANOVAs with JMP (RMS, with Subject as a random factor), I have noticed that when a certain factor is crossed with Subject, the corresponding DF Den stays independent while the DF Dens for the other factors are put together as “Residual”.  Please see Images 1-3 of the attached file on how “DF Den” under “Test Denominator Synthesis” change across imag...

  • Partition and Pruning

    I'm working with a dataset of about 27,000 rows and am trying to use 9 factors to predict a response using the partition function and a decision tree.  I'm using both k-means and validation.  When I tell JMP to Go, it will split 100-200 times, however the Split History shows me very little improvement after about 20 splits. For what I'm trying to do, I want to back up to the 20th split, but I don'...

  • I want to use LASSO and Group LASSO in JMP

    I'm involved in a project where we are applying lasso to build a logistic regression model from a "black box" set of predictors.  I need to get JMP Pro before trying out JMP's implementation.  I'm doing all the analysis in R at present.  Does JMP Pro also include group lasso?  I've found through using JMP Cluster Variables (CLUSVAR) that I can naturally group my predictors prior to group lasso.  F...
