| RSE {secr} | R Documentation |
Precision of parameter estimates from an SECR model, expressed as relative standard error.
RSE(fit, parm = NULL, newdata = NULL)
fit |
secr or openCR fitted model |
parm |
character; names of one or more real parameters (default all) |
newdata |
dataframe of covariates for |
The relative standard error (RSE) of parameter \theta is RSE(\hat \theta) = \widehat{SE} (\theta) / {\hat \theta}.
For a parameter estimated using a log link with single coefficient \beta, the RSE is also \mbox{RSE}(\hat \theta) = \sqrt {\exp( \mbox{var}(\beta))-1}.
This formula is used wherever applicable.
Named vector of RSE, or matrix if newdata has more than one row.
The less explicit abbreviation CV has been used for the same quantity (sometimes expressed as a percentage). CV is used also for the relative standard deviation of a distribution.
