title: What is this transformation called sqrt(max(x+1) - x)?
body: <p>so I had a response variable that was not normally distributed and was negatively skewed. So I tried many different approaches like using log, cube root but none did the trick. Finally I tried using sqrt(max(x+1) - x) and the distribution finally appeared to be normal. My problem is, I have read from some articles that the square root transformation is used for positively skewed data. Hence, my question is whether sqrt(max(x+1) - x) can be considered as a square root transform ? If not, what is it called then?</p>
