• How does JMP do BoxCox transformations?

  I have recently been converting JMP formulas into Excel using the python code option. I have been unable to actually transfer any formula (MLR) involving a BoxCox transformation. It have manually done the calculations following the formula and have gone numbers in the multimillions instead of 100 thousands where it should be. If someone knows if the formula is already converted back or If I need t...

• What is the relation between Fit Parametric Survival and Fit Life by X and how do I get alpha values?

  I am using Fit Parametric Survival with a weibull fit to several different groups of data (group 0 to group 19) with only location effect. Parallelly I am verifying the alpha values of the weibull fit to the different groups from Fit Life by X plot. I understand that in the Fit Parametric Survival plot, it takes the last group as the anchor point and calculates the intercept (not sure what exactly...

• Predictor screening always showing up as 0 contribution?

  All variables all showing up as 0 contribution. Whether in put 6 or 20 columns into the X variable selection, it always comes out as 0. I’m using a data point for everyday for the past ~5 years. Is there a specific reason why this is happening?

• I-optimal custom DOE RSM design with continuous and categorical factors - centre points not balanced?

  Hi, I want to create an I-optimal custom DOE with 5 continuous factors and one categorical factor (with 2 levels). I also want to have 4 centre points which I specify on set-up. I also choose RSM for my model as I know there is curvature. When JMP creates the design, the centre points are not equally divided across the two categorical levels - one category gets 4 centre points and the other gets 2...

• How does JMP Calculate Fixed Effects?

  I am comparing mixed model fixed effect calculations made in JMP versus R, attempting to produce similar results. I have been told JMP is using a Type III ANOVA. However, when I run a Type III in R (Wald Chisquare test), I get differing p values and sometimes different significant results. Additionally, the F ratio appears to replace the chi square value. Does anyone know what specific type of tes...
