Transformation from the Link Scale to the Observation Scale
The function transforms a variable from the link scale to the observation scale: probability or count.
invlink(x, type = c("cloglog", "log", "logit"))x |
A vector of real numbers. |
type |
A character string. Legal values are “cloglog”, “log” and “logit”. |
anti-logit(x) = exp(x) / (1 + exp(x))
anti-cloglog(x) = 1 - exp(-exp(x))
x <- seq(-5, 5, length = 100)
plot(x, invlink(x, type = "logit"),
type = "l", lwd = 2, ylab = "Probability")
lines(x, invlink(x, type = "cloglog"), lty = 2, lwd = 2)
grid(col = "black")
