mixSQP {ashr} | R Documentation |
Estimate mixture proportions of a mixture model using mix-SQP algorithm.
mixSQP(matrix_lik, prior, pi_init = NULL, control = list(), weights = NULL)
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 |
A list object including the estimates (pihat
) and a
flag (control
) indicating convergence success or failure.
