calcempirical_top: Empirically locate top and top concentration

In tcplfit2: A Concentration-Response Modeling Utility

Empirically locate top and top concentration

Description

Locate the top and the concentration at which top occurs empirically by sampling points within the experimental concentration range.

Usage

calcempirical_top(conc, ps, fname, precision = 100)

Arguments

conc	Vector of concentrations
ps	Vector of parameters, must be in order: a, tp, b, ga, p, la, q, er
fname	Model function name (equal to model name except hill which uses "hillfn")
precision	Number of points sampled on the base-10 logarithmic scaled experimental concentration range. (Defaults to 100.)

Value

A named list of the top and top concentration. The elements of the list are:

• top - empirical top

• x_top - concentration at which empirical top occurs

Examples

conc = c(.03,.1,.3,1,3,10,30,100)
ps = c(1,2,1,2,2)
fname = "gnls"
calcempirical_top(conc, ps, fname)
