LPxt {morseTKTD}R Documentation

Lethal Profile calculation

Description

Predict the Lethal Profile factor leading to $x$ % of reduction in survival at a specific time $t$.

Generic method for LPxt, a function denoted LP(x,t) for x\

Usage

lpxt(fit, x, ...)

## S3 method for class 'SurvFit'
lpxt(
  fit,
  x = 0.5,
  t = NULL,
  display.exposure = NULL,
  interpolate_length = NULL,
  max.steps = 100,
  accuracy = 0.01,
  ...
)

## S3 method for class 'LPxt'
update(object, accuracy = 0.01, max.steps = 100, ...)

Arguments

fit

An object used to select a method

x

rate of individuals dying (e.g., 0.5 for LP_{50}, 0.1 for LP_{10}, ...).

...

Further arguments to be passed to generic methods

t

A number giving the time at which LP_{x} has to be estimated. If NULL, the latest time point of the experiment is used.

display.exposure

A vector of the exposure porfile

interpolate_length

of time point in the range of concentration between 0 and the maximal concentration. 100 by default. description.

max.steps

max steps to find the LPxt

accuracy

accuracy of the LPxt algorithm (stop when reaching the accuracy).

object

An object of class LPx

Value

returns an object of class LPxt
