Can I log-transform attributes with different scales?
is it ok if I transform attributes that are skewed but have different scales? e.g. salaries data and age for a certain income group or so...
like to attributes that are both skewed, but where the scales are very different... or should I first normalize them and then log -transform?
does the transformation affect the scales in some way? and after log-transformation, should I still normalize them or is it not necessary anymore?
