is there any difference if we use log 10 and log value? How to use log value in smartpls ? My Dv is log value and IVs not..IVs use latent scores they are 2nd order construct
+simon renauld You may have a theoretical mathematical relationship between your Y and Xs, and this will determine what transformation you will do. For example, if your mathematical model is that there is an exponential relationship between Y and X in the form Y proportional to exp(X), then you would log both sides...if you are basing the choice soley on statistical properties and want the error term to be normal, then you can do: transform the Y but not the X, or do not transform Y and transform X, or transform both Y and X. The box-cox transformation is a power transformation that includes the log transform. The standard BC transform is for Y, where all the Y points are bigger than zero. Look it up, and good luck with your transforms - may the BC transform your life ;)
