create_training_data

Generates modeling data from a person-period data set.

utilities

A tool for survival analysis using a discrete time approach with ensemble binary classification. 'spect' provides a
simple interface consistent with commonly used R data analysis packages, such as 'caret', a variety of parameter options
to help facilitate search automation, a high degree of transparency to the end-user - all intermediate data sets and
parameters are made available for further analysis and useful, out-of-the-box visualizations of model performance. Methods
for transforming survival data into discrete-time are adapted from the 'autosurv' package by Suresh et al., (2022)
<doi:10.1186/s12874-022-01679-6>.

create_training_data function

<dl><dt>person_period_data</dt>
<dd>A discrete-time data set. Generally, this will be output
from the `create_person_period_data` function.</dd>
<dt>time_col</dt>
<dd>A string specifying the name of the column which contains the survival 
time.</dd>
<dt>event_col</dt>
<dd>A string specifying the name of the column which contains the event
indicator.</dd>
<dt>cens</dt>
<dd>Specifies how to apply censored data. Valid values are "same" - considers
censorship to occur in the same interval as the survival time, "prev" - considers
censorship to occur in the prior interval, and "half" - considers censorship to occur
in the same interval as survival time if the individual survived for at least half of
that interval.</dd></dl>
