get.extra.Estep.points

Function used to obtain extra theta values to be supplied to the
E-step in the next iteration (M_step.R). Note: this function should be
changed when implementing the sample space contractions (see comment made in
documentation of <code>M_step</code>).

Several statistical methods for analyzing survival data under various forms of dependent
censoring are implemented in the package. In addition to accounting for dependent censoring, it
offers tools to adjust for unmeasured confounding factors. The implemented approaches allow
users to estimate the dependency between survival time and dependent censoring time, based
solely on observed survival data. For more details on the methods, refer to Deresa and Van
