Q_function function

Q-function to replace log-likelihood function

Q_function(par, prob_log, omega_log, X, k, times)

Arguments

• par: numeric vector for parameters need to be estimated
• prob_log: mixture component weights(log)
• omega_log: latent variables(log)
• X: matrix for cluster
• k: vector for the cluster number
• times: vector for the x values or time points

Returns

the Loglikelihood value
