Thank you for responding.
There are no functions under (x) and I am familiar with LG10 but am no Statistician!!
Not sure if log (x + c) is the same as LG10 and have no idea what log(max(x,c)) for some constant c actually means. But hoping that you may.
I have continuous data that is positively skewed but with some zero and near zero values which I am advised need careful handling - hence the transformation prescription. Hope that makes sense?
