Can I detect outliers in Stata. A boxplot of my data shows extreme values and I cannot find a transformation to normality. I am unhappy at just discarding results because they are "extreme" and was wondering if there is an implimentation of Grubb's or Dixon's test, or indeed any more satisfactory test.
Thank you.
Janet.
