If you wish to reduce positive skewness in variable Y traditional transformation include log
NegSkew
12 oct. 2010 a negatively skewed variable had to be reflected (reversed) anchored at 1.0
Use this transformation method. Moderately positive skewness. Square-Root. NEWX = SQRT(X). Substantially positive skewness. Logarithmic (Log 10).

If it is negative then the distribution is skewed to the left or A logarithmic transformation may be useful in normalizing distributions that have.

For instance a logarithmic transformation is recommended for positively skewed data
MACE scores (n=599) illustrating rightward negative skew. means using log transformation of test scores to compensate for skewed data.
rather like the log transformation. As such this can be a useful way to reduce positive skew; however
