7.1.75. 3dErrtsCormatΒΆ

Link to classic view

Usage: 3dErrtsCormat [options] dset

Computes the correlation (not covariance) matrix corresponding to the residual (or error) time series in ‘dset’, which will usually be the ‘-errts’ output from 3dDeconvolve. The output is a 1D file of the Toeplitz entries (to stdout).

Options:

-concat rname = as in 3dDeconvolve
-input dset = alternate way of telling what dataset to read
-mask mset = mask dataset
-maxlag mm = set maximum lag
-polort pp = set polort level (default=0)

– RWCox – June 2008 – for my own pleasant purposes – Also see program 3dLocalCormat to do this on each voxel,

and optionally estimate the ARMA(1,1) model parameters.
