Note that this reference documentation is identical to the help that is displayed in Matlab when you type “help statistics_analytic”.

  STATISTICS_ANALYTIC performs a parametric statistical test on the
  data, based on a known (i.e. analytic) distribution of the test
  statistic. This function should not be called directly, instead
  you should call the function that is associated with the type of
  data on which you want to perform the test.
 
  Use as
    stat = ft_timelockstatistics(cfg, data1, data2, data3, ...)
    stat = ft_freqstatistics    (cfg, data1, data2, data3, ...)
    stat = ft_sourcestatistics  (cfg, data1, data2, data3, ...)
  where the data is obtained from FT_TIMELOCKANALYSIS, FT_FREQANALYSIS
  or FT_SOURCEANALYSIS respectively, or from FT_TIMELOCKGRANDAVERAGE,
  FT_FREQGRANDAVERAGE or FT_SOURCEGRANDAVERAGE respectively.
 
  The configuration can contain
    cfg.statistic        = string, statistic to compute for each sample or voxel (see below)
    cfg.correctm         = apply multiple-comparison correction, 'no', 'bonferoni', 'holms', 'fdr' (default = 'no')
    cfg.alpha            = critical value for rejecting the null-hypothesis (default = 0.05)
    cfg.tail             = -1, 1 or 0 (default = 0)
    cfg.ivar             = number or list with indices, independent variable(s)
    cfg.uvar             = number or list with indices, unit variable(s)
    cfg.wvar             = number or list with indices, within-block variable(s)
 
  The parametric statistic that is computed for each sample (and for
  which the analytic probability of the null-hypothesis is computed) is
  specified as
    cfg.statistic       = 'indepsamplesT'     independent samples T-statistic,
                          'indepsamplesF'     independent samples F-statistic,
                          'indepsamplesregrT' independent samples regression coefficient T-statistic,
                          'indepsamplesZcoh'  independent samples Z-statistic for coherence,
                          'depsamplesT'       dependent samples T-statistic,
                          'depsamplesF'       dependent samples F-statistic,
                          'depsamplesregrT'   dependent samples regression coefficient T-statistic,
                          'actvsblT'          activation versus baseline T-statistic.
