Summarize a continuous-time movement model
This function returns a list of biologically interesting parameters in human readable format, as derived from a continuous-time movement model.
Confidence level for parameter estimates.
Confidence level for the Gaussian home-range area.
If summary is called with a single
ctmm object output from
ctmm.fit, then a table is returned with low, maximum likelihood, and high estimates for the following possible parameters:
The autocorrelation timescales.
The Gaussian home-range area, where the point estimate has a significance level of
level.UD. I.e., the core home range is where the animal is located 50% of the time with
level.UD=0.50. This point estimate itself is subject to uncertainty, and is given confidence intervals derived from
The Gaussian root-mean-square (RMS) velocity, which is a convenient measure of average speed.
If summary is called on a list of
ctmm objects output from
ctmm.select, then a table is returned with the model names and AIC differences, where "IID" denotes the uncorrelated bi-variate Gaussian model, "OU" denotes the continuous-position Ornstein-Uhlenbeck model, and "OUF" denotes the continuous-velocity Ornstein-Uhlenbeck-F model.
Confidence intervals on the autocorrelation timescales assume they are sufficiently greater than zero and less than infinity.
