smm_fit_em {MixtureFitting} | R Documentation |
Estimate Student's t Mixture parameters using Expectation Maximization.
Description
Estimates parameters for Student's t mixture using Expectation Maximization algorithm. Calls smm_fit_em_APK10().
Usage
smm_fit_em( x, p, ... )
Arguments
x |
data vector |
p |
initialization vector of 4*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, ni1, ni2, ..., nin ), where Ai is the proportion of i-th component, mui is the center of i-th component, ki is the concentration of i-th component and nii is the degrees of freedom of i-th component. |
... |
additional arguments passed to smm_fit_em_GNL08(). |
Value
Vector of mixture parameters, whose structure is the same as of input parameter's p.
