Joel Bernstein updated SOLR-10991:
----------------------------------
Description:
Influential observations are *outliers* that have a large effect on the slope
of a regression line. It is very useful to be able to automatically remove
influential observations prior to running a simple regression.
Syntax:
{code}
regress(colA, colB, 10)
{code}
The function above regresses colA and colB after removing the top 10
influential observations from the data set.
was:Influential observations are outliers that have a large effect on the
