hierarchicalFWER | R Documentation |
Apply hierarchical test for each hierarchy, and test external variables for FWER control at level alpha
hierarchicalFWER(
X,
y,
group,
var,
test = partialFtest,
Shaffer = FALSE,
addRoot = FALSE
)
X |
original data |
y |
associated response |
group |
vector with index of groups. group[i] contains the index of the group of the variable var[i]. |
var |
vector with the variables contained in each group. group[i] contains the index of the group of the variable var[i]. |
test |
function for testing the nullity of a group of coefficients in linear regression.
The function has 3 arguments: |
Shaffer |
boolean, if TRUE, a Shaffer correction is performed |
addRoot |
If TRUE, add a common root containing all the groups |
Version of the hierarchical testing procedure of Meinshausen for MLGL output. You can use th selFWER function to select groups at a desired level alpha
a list containing:
pvalues of the different test (without correction)
adjusted pvalues
Index of the group
Matrix describing the hierarchical tree.
