A `matrix`

with low, maximum likelihood, and high estimates for the following parameters:

`area`

The home-range area with fraction of inclusion

`level.UD`

. E.g., the 50% core home range is estimated with`level.UD=0.50`

, and 95% confidence intervals are placed on that area estimate with`level=0.95`

.This kernel density estimate differs from the Gaussian estimate of

`summary.ctmm`

. The Gaussian estimate has more statistical efficiency, but is less related to space use for non-Gaussian processes.

Prior to `ctmm`

v0.3.1, AKDEs included only errors due to autocorrelation uncertainty, which are insignificant in cases such as IID data.
Starting in v0.3.1, `akde`

calculated an effective sample size `DOF.H`

and used this to estimate area uncertainty under a chi-square approxmation.
Starting in v0.3.2, this method was improved to use `DOF.area`

in the Gaussian reference function approximation.
