mlmfit: Accelerated Failure Time (AFT) Models with Random Effects
In frailtyHL: Frailty Models via Hierarchical Likelihood

mlmfit is used to fit linear mixed models with censoring by using h-likelihood.

1	mlmfit(jm1, data, weights, subset, na.action, Maxiter = 200)

`jm1`	This option requires `jointmodeling` object which specifies the AFT random-effect model.
`data`	dataframe containing the variables used in the jm1
`weights`	Vector of case weights.
`subset`	Expression indicating which subset of the rows of data should be used in the fit. All observations are included by default.
`na.action`	A missing-data filter function.
`Maxiter`	numeric, maximum number of iterations
