get_hazardRate: Get hazard rates

In Knusprikus/BSSRed: Blinded Sample Size Reestimation For Event Driven Trials

Usage

get_hazardRate(prop,time,theta=NULL)

get_eventProportion(hazard,time,theta=NULL)

get_eventProportion(hazard, time, theta = NULL)

Arguments

prop	a vector of numbers greater 0 and smaller 1 defining the proportion of patients having an event before 'time'.
time	a number defining the timeframe.
theta	optional number defining the hazard rate. Returning(-log(1-prop) /time * theta)
hazard	a vector of numbers greater 0 defining the hazard rates per timeintervall of length 1.

Value

a vector defining the hazard rate per timeintevall of length 1.

Examples

# Assuming, that 30% of patients in the control group have an event after 24 month,
# the monthly hazard rate for the control group can be calculated by:
get_hazardRate(.3,24)

# With a assumed reduction of the hazard by 30% in the treatment group we can calculate
# the hazard rate as follows:
get_hazardRate(.3,24,1-.3)
