gaussianPercentile

Return to directory of Todd's tools

Builds a Gaussian distribution, then computes the standard deviation and MAD of the values below the specified percentile. See also gaussianPercentilePlot.

Usage:

tt.gaussianPercentile(percentile, N=100000)

Returns: st. dev., MAD, fraction of points selected, offset, where offset is the difference between the median of all the data and the median of the selected points, divided by the MAD

Example:

CASA <4>: tt.gaussianPercentile(20)
Median of all data=-0.001873, median of selected points=-1.287488
  Out[4]: (0.46566450349936794, 0.41599508032921984, 1e-05, 3.0904569574556406)
