Compute the log-rank test p-value for the difference between the two survival curves obtained by splitting a dataset into a "low" and "high" risk group using a given relative-risk threshold.
Arguments
- input_data
A tbl_df or data.frame in which each observation is a row.
- relative_risk_col
An unquote column name indicating which column contains the relative-risk estimates for each observation.
- time_col
An unquoted column name indicating which column contains the true time-to-event information for each observation.
- event_col
An unquoted column name indicating which column contains the outcome (event or censorship). Must be a binary column - all values should be either 0 or 1 (with 1 indicating the adverse event and 0 indicating censorship) or FALSE and TRUE (with TRUE indicating the adverse event and FALSE indicating censorship).
- threshold
A numeric value indicating the relative-risk threshold that should be used to split observations into low- and high-risk groups.
