Note that this reference documentation is identical to the help that is displayed in Matlab when you type “help statfun_depsamplesregrT”.
STATFUN_depsamplesregrT calculates dependent samples regression T-statistic
on the biological data in dat (the dependent variable), using the information on
the independent variable (iv) in design.
Use this function by calling one of the high-level statistics functions as:
[stat] = ft_timelockstatistics(cfg, timelock1, timelock2, ...)
[stat] = ft_freqstatistics(cfg, freq1, freq2, ...)
[stat] = ft_sourcestatistics(cfg, source1, source2, ...)
with the following configuration option:
cfg.statistic = 'depsamplesregrT'
see FT_TIMELOCKSTATISTICS, FT_FREQSTATISTICS or FT_SOURCESTATISTICS for details.
For low-level use, the external interface of this function has to be
[s,cfg] = statfun_depsamplesregrT(cfg, dat, design);
where
dat contains the biological data, Nsamples x Nreplications
design contains the independent variable (iv) and the unit-of-observation (UO)
factor, Nreplications x Nvar
Configuration options:
cfg.computestat = 'yes' or 'no', calculate the statistic (default='yes')
cfg.computecritval = 'yes' or 'no', calculate the critical values of the test statistics (default='no')
cfg.computeprob = 'yes' or 'no', calculate the p-values (default='no')
The following options are relevant if cfg.computecritval='yes' and/or
cfg.computeprob='yes'.
cfg.alpha = critical alpha-level of the statistical test (default=0.05)
cfg.tail = -1, 0, or 1, left, two-sided, or right (default=1)
cfg.tail in combination with cfg.computecritval='yes'
determines whether the critical value is computed at
quantile cfg.alpha (with cfg.tail=-1), at quantiles
cfg.alpha/2 and (1-cfg.alpha/2) (with cfg.tail=0), or at
quantile (1-cfg.alpha) (with cfg.tail=1).
Design specification:
cfg.ivar = row number of the design that contains the independent variable.
cfg.uvar = row number of design that contains the labels of the UOs (subjects or trials)
(default=2). The labels are assumed to be integers ranging from 1 to
the number of UOs.
