• Boosted Tree - Tuning TABLE DESIGN

  I selected Boosted Tree or a regression problem after it came as the best-performing model in model screening.  May I ask how to use the tuning table design to further optimize the performance of boosted tree?

• Calculation a p-value in a data table (regression) using row formulae

  Background: Suppose I have rows of x, y data (SN_C, Value [Sigma Units]) as shown in attached file but also pasted below.   Slope_8 is calculated from the previous 8 [x.y] values. I want to compare the slope_8 value to the null hypothesis for linear regression (slope =0) and provide a p-value. Is there an easy way to do this? The formula for the slope 8 was taken from these discussion boards (@txn...

• Error message for Neural Net With Missing Validation Rows - Suggest Workaround?

  Hello community, I am testing several models as part of JSL loop in JMP 16, using different validation columns to determine how the R2 values change depending on what data is used.  Each validation column contains a subset of the data, with some missing data at the beginning and/or the end of the column.  Other models, such as the Bootstrap, run well simply ignoring missing values but the Neural N...

• Weibull model for bacterial decay

  I have been asked to do a linear regression using Weibull on jmp. It only seems to work for data with a positive curve (growth), however, when trying to select the Weibull for the decay data it cannot be selected. Is there a parameter I am missing or an assumption that doesn't allow me to use this model?
