Hello guys,    Currently, I am doing one project on SAS Enterprise Miner, just needed one help while doing modelling I faced an issue of skewness with my continuous variables for which I firstly transformed into log but it didn't work but when changing it into square I got my answer and skewness issue was solved further I did modeling and the result was very extreme, my target variable was estimation of sales basically continuous, and modeling approach was linear regression, but I got validation average square error as 116 so  I am confused how to interpret  such huge error secondly when the same transformation is done through log the error rate is 0.25 but the continuous variable is not skewed.   Please, your efforts will be appreciated.   Thank You in advance.   ...
