gmm_init_vector_quantile {MixtureFitting} | R Documentation |
Estimate Gaussian Mixture parameters using Expectation Maximization.
Description
Estimate an initialization vector for Gaussian mixture fitting using (weighted) quantiles. Proportions and scales are set to equal, centers are placed at equispaced quantiles.
Usage
gmm_init_vector_quantile( x, m, w = numeric() )
Arguments
x |
data vector |
m |
number of mixture components |
w |
weight vector |
Value
Parameter vector of 3*n parameters, where n is number of mixture components. Structure of p vector is p = c( A1, A2, ..., An, mu1, mu2, ..., mun, sigma1, sigma2, ..., sigman ), where Ai is the proportion of i-th component, mui is the location of i-th component, sigmai is the scale of i-th component.
