survival {cvasi}

Survival rate

Description

Derives the survival rate of individuals for Reduced GUTS models

Usage

survival(scenario, ...)

Arguments

scenario

an EffectScenario to simulate

...

additional parameters passed on to simulate()

Details

The survival rate describes the survival probability at each time point. The function simulates the GUTS scenario and appends a column survival to the simulation result. A value of one (1.0) denotes that all individuals survive. A value of zero (0.0) denotes that no individuals survived.

Only available for Reduced GUTS models, see GUTS-RED-models. The equations were described by EFSA (2018).

Value

a data.frame containing simulation results

Examples

# calculate survival rate
minnow_it %>% survival()

# plot survival over time based on a random exposure profile
minnow_sd %>%
  set_exposure(data.frame(t=1:100, c=runif(100)*10)) %>%
  survival() -> df
plot(df$time, df$survival, "l")
