mvgc_confint

Confidence intervals for sample MVGC based on theoretical asymptotic distribution

Syntax

   [xup,xlo] = mvgc_confint(alpha,x,p,m,N,nx,ny,nz,tstat)

Arguments

See also Common variable names and data structures.

input

   alpha      significance level (scalar)
   x          matrix of MVGC values
   p          VAR model order
   m          number of observations per trial
   N          number of trials
   nx         number of target ("to") variables
   ny         number of source ("from") variables
   nz         number of conditioning variables (default: 0)
   tstat      statistic: 'F' or 'chi2' (default: 'F' if nx == 1, else 'chi2')

output

   xup        matrix of upper confidence bounds
   xlo        matrix of lower confidence bounds

Description

Return upper and lower confidence bounds [xup,xlo] at significance level alpha for sample MVGCs in x, based on theoretical (asymptotic) distributions. NaN s are ignored. See mvgc_cdfi for details of other parameters.
