vmm_init_vector {MixtureFitting} | R Documentation |
Estimate von Mises Mixture parameters using Expectation Maximization.
Description
Estimate an initialization vector for von Mises mixture fitting via Expectation Maximization. Proportions are set to equal, centers are equispaced through the whole domain of input sample, and concentrations are set to (m/(12*180))^2.
Usage
vmm_init_vector( m, implementation = "C" )
Arguments
m |
number of mixture components |
implementation |
flag to switch between C (default) and R implementations. |
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, k1, k2, ..., kn ), where Ai is the proportion of i-th component, mui is the center of i-th component and ki is the concentration of i-th component.
