Logistic function

Logistic function of the form $(1 + exp(-\beta * (x - \alpha)))^(-1)$

logistic_fun(x, p)

Arguments

• x: Vector of values of the explanatory variable.
• p: Vector of parameters $p = c(\alpha, \beta)$.

Returns

Probability at each x.

Examples

xseq <- seq(0, 4, .01)
yseq <- logistic_fun(xseq, c(2, 4))
curve <- data.frame(x = xseq, y = yseq)
ggplot(curve, aes(x = x, y = y)) + geom_line()
