negbin.rel.pca: Relative Likelihood based PCA assuming Negative Binomial...

In marl: Multivariate Analysis Based on Relative Likelihoods

Description

The function performs PCA on matrix based on weighted relative likelihood function and provides a plot of first two PCs as well as summary of PCA.

Usage

negbin.rel.pca(x, mu.min, mu.max, len = 200, plot = TRUE, seed = 132)

Arguments

x	Observations of length greater than 1. Data can be entered as matrix or list.
mu.min	Minimum value of mean for the relative likelihood function.
mu.max	Maximum value of mean for the relative likelihood function.
len	Length of values to be evaluated at in between mu.min and mu.max.
plot	If set TRUE, provides plot of weighted relative likelihood functions colored by their cluster assignment.
seed	Seed to be set for reproducibility
