Survival Function for Different Transition Models

Survival Function for Different Transition Models

Usage

survTrans(transition, t, trans)

# S3 method for class 'ExponentialTransition'
survTrans(transition, t, trans)

# S3 method for class 'WeibullTransition'
survTrans(transition, t, trans)

Arguments

transition

(ExponentialTransition or WeibullTransition)
see exponential_transition() or weibull_transition() for details.

t

(numeric)
time at which survival probability is to be computed.

trans

(integer)
index specifying the transition type.

Value

The survival probability for the specified transition and time.

Methods (by class)

• survTrans(ExponentialTransition): for the Exponential Transition Model

• survTrans(WeibullTransition): for the Weibull Transition Model

Examples

transition <- exponential_transition(h01 = 1.2, h02 = 1.5, h12 = 1.6)
survTrans(transition, 0.4, 2)
#> [1] 0.5488116
transition <- exponential_transition(h01 = 1.2, h02 = 1.5, h12 = 1.6)
survTrans(transition, 0.4, 2)
#> [1] 0.5488116
transition <- weibull_transition(h01 = 1.2, h02 = 1.5, h12 = 1.6, p01 = 2, p02 = 2.5, p12 = 3)
survTrans(transition, 0.4, 2)
#> [1] 0.8591693
