test.l.max {EMMAgeo} | R Documentation |
Find maximum possible wight transformation value.
Description
This function approximates the highest possible value for l in a nested
loop. It uses test.l
and does not need any further parameters. It
starts with l between zero and 0.5 and iteratively approximates the last
possible vlaues for which the weight-transformed matrix of the input data
still allows eigenspace extraction.
Usage
test.l.max(X, n = 10, ...)
Arguments

Value
Numeric
scalar, maximal possible l value.
