@b@cRemove Outliers

@bDescription

The Remove Outliers filter replaces all observations that lie more than
three standard deviations from the mean with the current value for a missing
observation. 

@bNotes

The parameter 3 (for standard deviations) should be user configurable. It
isn't yet.


@b@cDetrend 

@bDescription

The Detrend filter calculates any linear trend in the specified variable(s),
and removes that trend from the data. When multiple variables are selected,
a seperate trend calculation is made for each.

@bNotes

The existing data is overwritten, so if you want to have both non-detrended
and detrended variables in the same dataset, make a copy first (using the
Generate command).


@b@cTransform 0-1

@bDescription

This filter simply transforms the data so that the largest observation is
1.0, the smallest is 0.0, and all other values are scaled to fit in this
range. This can be useful for fitting different variables onto a single
graph. The GA-Fit routine also seems to perform better when it's fed data in
this format (but you'll probably want to reduce MaxReal from its default
value).

@bNotes

The existing data is overwritten, so if you want to have both non-0-1
and 0-1 variables in the same dataset, make a copy first (using the
Generate command).
