MSARmdl_em function

Estimation of Markov-switching autoregressive model by EM Algorithm

Estimate Markov-switching autoregressive model by EM algorithm. This function is used by MSARmdl which organizes the output and takes raw data as input.

MSARmdl_em(theta_0, mdl, k, optim_options)

Arguments

• theta_0: vector with initial values for parameters.
• mdl: List with model attributes.
• k: Integer determining the number of regimes.
• optim_options: List with optimization options.

Returns

List with model results.
