draw.sv.init

Used in the M-step (get.starting.values.R). ToDo: Adapt this
code so as to also perform sample space contractions as in the MatLab
implementation of Bei (2024).

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
Keilegom (2021) <doi:10.1093/biomet/asaa095>, Czado and Van Keilegom (2023)

draw.sv.init function

<dl><dt>theta.hash</dt>
<dd>Tentative optimal value for theta, i.e., the largest or
smallest feasible value for theta (if dir = 1 or dir = -1, respectively). A
'feasible value' is one that satisfies all moment restrictions.</dd>
<dt>dir</dt>
<dd>Search direction. <code>dir = 1</code> corresponds to looking for an
upper bound. <code>dir = -1</code> corresponds to looking for a lower bound.</dd>
<dt>hyperparams</dt>
<dd>List of hyperparameters.</dd>
<dt>EI.fun</dt>
<dd>Function used to compute the expected improvement. See also
<code>EI</code>.</dd></dl>

Arguments

Draw initial set of starting values for optimizing the expected
improvement. — draw.sv.init
