JMP offer 4 options, refit with transform replace with transform, save best transformation, and sav specific transformation, which one is suitable.</SPAN></P> Sat, 13 Sep 2025 09:48:21 GMT https://community.jmp.com/t5/Discussions/How-I-get-best-transformation-using-box-cox-transformation/m-p/900180#M106017 Keshav 2025-09-13T09:48:21Z https://community.jmp.com/t5/Discussions/How-I-get-best-transformation-using-box-cox-transformation/m-p/900211#M106019 <P>Hi <a href="https://community.jmp.com/t5/user/viewprofilepage/user-id/77065">@Keshav</a>,<BR /><BR />Welcome in the Community !<BR />I think you can find the answer in the <A href="https://www.jmp.com/support/help/en/18.2/#page/jmp/boxcox-y-transformation.shtml" target="_self">documentation</A>.<BR /><BR />To summarize, the first three options are different display/use/save of the best transformation found, whereas the last one enable you to manually change the lambda coefficient (so manually change the transformation):</P> <UL> <LI>Refit will relaunch the modeling with the best transformation in another window,</LI> <LI>Replace will modify the model from the already opened window with the best transformation,</LI> <LI>Save best transformation will save a prediction formula column in your datable (with the best lamba coefficient found for the transformation),</LI> <LI>Save specific transformation enable you to specify the lambda coefficient and save this transformation prediction formula with this specific transformation in your datatable.</LI> </UL> <P>&nbsp;</P> <P>Hope this answer will clarify the available options,</P> Sat, 13 Sep 2025 13:45:29 GMT https://community.jmp.com/t5/Discussions/How-I-get-best-transformation-using-box-cox-transformation/m-p/900211#M106019 Victor_G 2025-09-13T13:45:29Z
