pomp development version 3.1.1.1 has just been released on the package github site.
This release introduces the profile_design function, which is intended to replace profileDesign.
The so-called profile design consists of a series of slices through a parameter space perpendicular to one or more coordinate axes.
The old behavior was to generate a single set of points in one of these slices (randomly according to a uniform distribution when type="runif" and according to a sub-random (Sobol’) sequence when type="sobol") and then copy these points across all slices.
Thus, in a projection perpendicular to the slices, all nprof generated points would lie atop one another.
The new behavior is to generate the points in each slice independently.
Thus, a projection perpendicular to the slices will display n*nprof points, where n is the number of slices.
For stylistic reasons, the other design functions, sliceDesign, runifDesign, and sobolDesign have been replaced by slice_design, runif_design, and sobol_design, respectively.
The older functions remain in place, but are deprecated and will be removed in a future release.
