ploss: Calculate Loss (1-Utility)
In jiyingz/clinicalMPI: The novel modified probability interval (mPI) phase I clinical trial design
ploss R Documentation
Calculate Loss (1-Utility)
Description
Calculates loss for a given value with target and tolerance levels. Can be used for toxicity or futility.
Loss = 0 if value below target - tolerance, 1 if above target + tolerance, and linear from 0 to 1 between.
Usage
ploss(value = 0.18, target = 0.2, tolerance = 0.05) #calculate loss for 0.18 when equivalence interval is [0.15,0.25]
Arguments
value
Estimated probability of futility/toxicity
target
Target chance of futility/toxicity
tolerance
Half-length of the equivalence interval
Value
Calculated numeric loss for given value
