jac.invlogit {bisque} | R Documentation |
Jacobian for logit transform
Description
Let X=logit^{-1}(Y)
be a transformation of a random variable Y
.
This function computes the jacobian J(x)
when using the density of
Y
to evaluate the density of X
via
f(x) = f_y(logit(x)) J(x)
where
J(x) = d/dx logit(x).
Usage
jac.invlogit(x, log = TRUE)
Arguments
x |
value at which to evaluate |
log |
TRUE to return |
Examples
jac.invlogit(1)
