This function returns a list of biologically interesting parameters in human readable format, as derived from an autocorrelated kernel density estimate.
Confidence level for the above area estimate. E.g., the 95% confidence interval of the 50% core area.
Coverage level for the home-range area. E.g., the 50% core area.

level.UD=0.50, and 95% confidence intervals are placed on that area estimate with
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.
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.
