[Prob,T] = lyngby_ts_main(P, X, arg1, arg2, arg3, arg4)
lyngby_ts_main - Whole volume Student's t-test for equal variances.
function [Prob,T] = lyngby_ts_main(P, X, 'PropertyName',
Input: P Paradigm
Property: EdgeDrop The number of scans to discard at the
transitions of the paradigm
Output: Prob Probability (p-value)
T Student's unpaired t-value
This function gives the probability that Student's t
calculated on data X1 and X2, sampled from distributions
with the same variance, is higher than observed, i.e.
the "significance" level. This is used to test whether
two sample have significantly different means.
The whole volume is tested (compare with lyngby_ts_ttest)
and X1 are taken from the on-periods and X2 from the off-periods.
A number of scans (edgedrop) can be left out of the analysis
in order to accommodate to the heamodynamical response time.
The smaller P is, the more significant the difference between
the means. E.g. if P = 0.05 or 0.01, it is very likely that
the two sets are sampled from distributions with different
This assumes that the samples are drawn from distributions with
the SAME VARIANCE. The test is unpaired.
