## 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 |

`weights` |
The weights to be assigned to the observations. Must
be a vector of length equal the number of rows of |

### Value

A list object including the estimates (`pihat`

) and a
flag (`control`

) indicating convergence success or failure.
