Have a look at our newly updated YouTube channel – we’ve added 2 new videos today, an introduction to FlexParamCurve and a subsequent tutorial.
In the introductory video, Steve Oswald (Penn State) and Andre Chiaradia (Phillip Island) discuss how ‘FlexParamCurve’ makes nonlinear curve fitting accessible for non-monotonic parametric curves, through automated curve selection and parametrisation in a mixed effects model framework. They visit Phillip Island’s Penguin Parade to introduce avian growth as one application.
In the R tutorial, Steve walks us through coded examples of FlexParamCurve’s main functionality: selecting which curve to use, fitting/plotting, and analyzing in nlme().
