Description

Get the Hill coefficient of a 4-parmeter log-logistic function

Usage

1
getHillSlope(fit, CI95 = FALSE)

Arguments

fit

An object of class drc fit with drm() and the argument fct = LL.4().

CI95

Logical. Report 95% confidence interval.

Value

The Hill coefficient: y=c+\frac{d-c}{1+10^{(ln(\tilde{e})-x) \times Hill}}. Where c = upper asymptote, d = lower asymptote, and \tilde{e} = the EC50 value.

Examples

1
2
fit <- drc::drm(disp~wt, data=mtcars, fct=drc::LL.4())
getEC50(fit)
