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.
