Distribution-free Permutation Scale Tests in a Stratified One-Way Layout
Description
Permutation tests for scale parameters in the distribution-free stratified K-sample one-way layout for binary, ordinal, numeric and potentially independently right-censored outcomes.
Usage
scaleTest(object, B = 0, ...)
Arguments
object |
an object of class |
B |
an integer specifying the number of replicates used in the
permutation test. The default ( |
... |
additional parameters, currently ignored. |
Details
The distribution function F_1 of the response in the control group
(defined by the first factor level of the grouping factor groups) is
compared to the distribution functions in the remaining groups F_k for
k = 2, \dots, K. No assumptions are made regarding the form of F_1,
and thus inference is distribution-free. However, a
semiparametric model assumes that each distribution function F_k only
depends on F_1 and a scalar parameter \xi_k. The link
function Q defines the scale model
F_k(y) = Q^{-1}(Q(F_1(y)) / \exp(\xi_k))
for testing H_0^k: \xi_k = 0, k = 2, \dots, K. Under the null, the
model is fitted using free1way and permutation tests are reported.
Value
An object of class htest.
