(2017) Bringing the analysis of animal orientation data full circle: model-based approaches with maximum likelihood. Circular Statistics in Biology Academic Press, London 519.5202457400000 Aldenderfer,M.S.

Added a plotting function to visualize the observed and modeled resultsįitak, R.

Added support for data vectors with the “geographics” template set when plotting the modeled results.

Improved communication between CircMLE and R ‘circular’ objects, especially for improved plotting when using ‘template = “geographics”’.

Added the ability to perform the Hermans-Rasson and Pycke tests using code kindly provided by Lukas Landler, Graeme Ruxton, and E.Thanks Oliver Mitesser (University of Wörzburg) for the recommendation!.the model fitting function now includes the hessian matrix, and a function ci_circmle to calculate 95% confidence intervals for the MLE parameters.Thanks Matt Robinson for the great ideas and discussion! Added the circular distance correlation function.Load the package into your working R environment using library(CircMLE).

Then install the CircMLE package using install.packages("CircMLE").

First install the R package ‘circular’ from CRAN using the command install.packages("circular").

r:O is the modified Bessel function of the first kind and order zero.

Calculate the Hermans-Rasson test or Pycke test for directionality prediction is clearly as important in the context of directional data as it is for.

Plot the observed dataset and any of the model-fitted results.

Compare any two nested models using a likelihood ratio test.

Calculate the likelihood of any one or all of the 10 models of orientation.

This framework is designed for modeling any dataset represented by angles (e.g, orientation, periodic, etc) using the above models. The functions also include the ability to use different optimizer methods and calculate various model selection metrics (i.e., AIC, AICc, BIC).
