Routine to test statistical assumptions are met at each voxel for t-tests
1 2 | checkAssumptions_ttest(lesmat, behavior, assumptionThreshold = 0.05,
showInfo = TRUE, ...)
|
lesmat |
binary matrix (0/1) of voxels (columns) and subjects (rows). |
behavior |
vector of behavioral scores. |
assumptionThreshold |
(default=0.05) threshold to establish whether tests pass or fail. This threshold is applied at each voxel individually, no corretion for multiple comparison is applied. |
showInfo |
logical (default=TRUE), display info messages |
... |
arguments that are passed by upstream functions |
List of objects returned:
failVarianceTest
- vector of logical values
marking voxels that have different variance of behavioral
scores in lesioned and non-lesioned individuals. Obtained
using the var.test
function.
failNormalityTest
- vector of logical values
marking voxels with abnormal distribution of behavioral
scores either in lesioned or non-lesioned individuals.
Obtained with the shapiro.test
function.
