mixSQP {ashr} R Documentation

## Estimate mixture proportions of a mixture model using mix-SQP algorithm.

### Description

Estimate mixture proportions of a mixture model using mix-SQP algorithm.

### Usage

mixSQP(matrix_lik, prior, pi_init = NULL, control = list(), weights = NULL)


### Arguments

 matrix_lik A matrix containing the conditional likelihood values, possibly normalized. prior A vector of the parameters of the Dirichlet prior on the mixture weights. pi_init The initial estimate of the mixture weights. control A list of settings for the mix-SQP optimization algorithm; see mixsqp for details. weights The weights to be assigned to the observations. Must be a vector of length equal the number of rows of matrix_lik. If weights = NULL, all observations are assigned the same weight.

### Value

A list object including the estimates (pihat) and a flag (control) indicating convergence success or failure.
