interp_ED50: Starting value calculation for ED50 parameter
In jcduda/td2pLL: Fitting a time-dose two-parameter log-logistic model to time-dose-response data
interp_ED50 R Documentation
Starting value calculation for ED50 parameter
Description
Calculates cheap starting parameter for the ED50 parameter of a
2pLL model by interpolation. This function is used in get_starting_values.
Usage
interp_ED50(data = NULL)
Arguments
data
(numeric data.frame())
A data frame with columns dose for the dose values and mean_resp
as (mean) response for a given dose value.
of mean response data at given dose level.
Details
The function assumes that the mean response values lay within 0 and
100, i.e. have percent units.
It also assumes a downward trend of the ED50 with dose.
If the lowest mean_resp value is already above 50, the function
returns the maximal dose.
Value
Returns the numeric ED50_interp.
