Feature request: add data requirements section for algorithms

[snowch]

It would be really useful if the descriptions for linear regression, logistic regression and algorithms had a section that described data requirements/expectations. For example, from what I understand, least squares estimates for regression models are highly sensitive to (not robust against) outliers.

Great idea. Do you want to take a crack at it? I'll leave this open as a feature request anyway for someone to tackle.
