Transformed (logarithmized variables)

[Jerry007]

Hi,

my skewness at some variables (items) were pretty bad ( above 1 or -1) so I logarithmized the specific ones.
Now I´m modelling and have 4 factors having around 4-6 items each.
Some of the item were logarithmized, some were not.

My first question: could that be a problem using logarithmized and NOT logarithmized items at the same time?

My second question: Do I have do anything else? Cause the Min and Max values of a construct with logarithmized and not logarithmized values differ obviously now...

Kind regards & Thanks

Jerry

I would not mix log and non-log variables in one construct. It will be hard (impossible) to interpret.
Either log all or none of the indicators for one constructs.

Different constructs can of course have log and non-log indicators, but not mix them in the same construct.
