pdLMS: Plot frequency distributions(s) for given L, M and S values in LMS method
Description
The LMS method defines frequency distributions in terms of L, M and S parameters.
pdLMS plots one or more LMS distributions and optionally returns specified
centiles on each distribution.
Usage
pdLMS(L = 1, M = 1, S = 0.2, zcent = NULL, zlim = 3.5,
N = 1000, plot = TRUE, ...)
Arguments
L
vector of Box-Cox transformation (lambda) values, L in the LMS
method (default 1 corresponding to the Normal distribution).
M
vector of medians (mu), M in the LMS method (default 1).
S
vector of coefficients of variation (sigma), S in the LMS method
(default 0.2).
zcent
optional vector of z-scores for conversion to the measurement
scale under each distribution.
