Locally Best Invariant (LBI) Additivity Test
Description
Test for an interaction in two-way ANOVA table by the LBI test.
Usage
lbi.test(Y, alpha = 0.05, critical.value = NA, Nsim = 1000)
Arguments
Y |
data matrix |
alpha |
level of the test |
critical.value |
result of |
Nsim |
number of simulations to be used for a critical value estimation |
Details
The critical value can be computed in advance and given in the parameter critical value
.
If not a function critical.values
is called to do that.
Value
A list with class "aTest
" containing the following components:
test statistics stat
, critical value critical.value
and the result of
the test result
, i.e. whether the additivity hypothesis has been rejected.
