For deriv = 0
, the log of theta
, i.e., log(theta)
when inverse = FALSE
, and if inverse = TRUE
then
exp(theta)
.
For deriv = 1
, then the function returns
d theta
/ d eta
as a function of theta
if inverse = FALSE
,
else if inverse = TRUE
then it returns the reciprocal.Here, all logarithms are natural logarithms, i.e., to base $e$.
theta
close to 0 or out of range
result in
Inf
, -Inf
, NA
or NaN
. The function loge
computes
$\log(\theta)$ whereas nloge
computes
$-\log(\theta)=\log(1/\theta)$.
