Class for the definition of piecewise survival times.

Details

PiecewiseSurvivalTime is a class for the definition of piecewise survival times.

piecewiseSurvivalTime: The time intervals for the piecewise definition of the exponential survival time cumulative distribution function. Is a numeric vector.
lambda1: The assumed hazard rate in the treatment group. Is a numeric vector of length kMax.
lambda2: The assumed hazard rate in the reference group. Is a single numeric value.
hazardRatio: The hazard ratios under consideration. Is a numeric vector of length kMax.
pi1: The assumed event rate in the treatment group. Is a numeric vector of length kMax containing values between 0 and 1.
pi2: The assumed event rate in the control group. Is a single numeric value between 0 and 1.
median1: The assumed median survival time in the treatment group. Is a numeric vector.
median2: The assumed median survival time in the reference group. Is a single numeric value.
eventTime: The assumed time under which the event rates are calculated. Is a single numeric value.
kappa: The shape of the Weibull distribution if kappa!=1. Is a single numeric value.
piecewiseSurvivalEnabled: Indicates whether specification of piecewise definition of survival time is selected. Is a single logical value.
delayedResponseAllowed: If TRUE, delayed response is allowed, if FALSE the response is not delayed.
delayedResponseEnabled: If TRUE, delayed response is enabled, if FALSE delayed response is not enabled.
