Description Usage Arguments Value Examples
Method to initialize EM parameters. Carries out a single GLM fit and applies random noise to form starting space.

y |
A vector of observation of length n. |
x |
An n-by-p design matrix. |
K |
Number of EM classes to be fit. |
weight |
A n length vector of observation weight terms. This is currently designed to be either the exposure for a Poisson model or the number of trials for a Logistic model. |
family |
GLM family to fit. |
noise |
Standard deviation of the white noise to be applied when generating random initial states. |
A K-length list, each holding parameters.
1 2 3 4 | x <- model.matrix(~ 1 + factor(wool) + factor(tension), data = warpbreaks)
y <- warpbreaks$breaks
init.fit(y = y, x = x, K = 2)
