Logit (log-odds) and inverse-logit function.
Description
Calculates the logit (log-odds) and inverse-logit.
Usage
logit(mu)
inv_logit(eta)
Arguments
mu |
A numeric object with probabilies, with values in the in
the range |
eta |
A numeric object with log-odds values, with values in
the range |
Details
Values of mu equal to 0 or 1 will return -\infty
or
\infty
respectively.
Value
A numeric object of the same type as mu and eta containing the logits or inverse logit of the input values. The logit and inverse transformation equates to
\text{logit}(\mu) = \log(\mu/(1-\mu))
\text{logit}^{-1}(\eta)= \exp(\eta)/(1 + \exp(\eta)).
Examples
logit(0.2)
inv_logit(-1.386)
