|---|---|
| AstCorrelation |
Calculate Pearson's Correlation Coefficient between columns of a frame
Formula:
Pearson's Correlation Coefficient = Cov(X,Y)/sigma(X) * sigma(Y)
|
| AstDistance |
Calculate Distance Metric between pairs of rows

| AstHist.ThirdMomTask | |
| AstImpute |
Impute columns of a data frame in place.
|

| AstTable |
Variance between columns of a frame
TODO: Define "table" in terms of "groupby"
TODO: keep dense format for two-column comparison (like in previous version of Rapids)
(table X Y) ==>
(groupby (cbind X Y) [X Y] nrow TRUE)
