• To validate a model, can I compare the optimal conditions with that of the same model with 6 new runs added?

  Here are the optimal conditions for the model comprised of 15 Box Behnken design runs with standard least squares.  The optimal conditions for the model comprised of the same 15 Box Behnken design runs + 6 new runs, yield nearly the same optimal conditions with a slightly lower defect rate to fall within the spec limits.   Could it be statistically justifiable to compare the optimal conditions of ...

• How to perform k-fold cross-validation on ML models (e.g. neural network and random forest) and check model performance on fixed test data?

  I have classification dataset on which I want to fit neural network and random forest model. I am performing the k-fold cross validation for selecting best model.I have separate data (fixed test data) on which I want to test the model performance. How can I pass that data to JMP and get classification report?

• 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...
