TCEM: Threshold Concentration Effect Model

Description Usage Arguments Value

View source: R/TCEM.R

Description

This simplified effects model uses an lethal concentration for a given percent of the population to determine threshold type effects. Specifically, a concentration 'lc_conc' and an associated percent 'lc_percent' combined with a time series of daily exposures and when the 'exposure_concentrations' exceed the 'lc_conc' value, there is an 'lc_percent' decrease in survival that day.

Usage

1
TCEM(exposure_concentrations, lc_conc, lc_percent)

Arguments

lc_conc

Lethal concentration for 'lc_percent' [float]

lc_percent

Percentage lethality in population for 'lc_conc' [float]

Value

Time series of survival decrements for the associated 'exposure_concentrations' time series. [vector]
