Description

Class for the definition of piecewise survival times.

Details

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

Fields

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 numeric vector of length 1.

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 numeric vector of length 1 containing a 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 numeric vector of length 1.

eventTime

The assumed time under which the event rates are calculated. Is a numeric vector of length 1.

kappa

The shape of the Weibull distribution if kappa!=1. Is a numeric vector of length 1.

piecewiseSurvivalEnabled

Indicates whether specification of piecewise definition of survival time is selected. Is a logical vector of length 1.

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.
