- Added a
NEWS.mdfile to track changes to the package.
- Preparing for first release to CRAN
- Added Erin McDonnell as an author
- Erin McDonnel added non-parametric updates
- Updated vignette as well
- Use of periodic b-splines
- get her to implement gradient for parametric warping stuff
- registr is now able to handle incomplete curves (see new vignette)
- Added 'two-step GFPCA' as alternative GFPCA approach
- New plot function for GFPCA results
- Parallelized the registration call
- Added user-specified template functions by argument 'Y_template'
- Added Gamma and Poisson family
- Added Alexander Bauer an an author
- Changed convergence threshold in register_fpca from 0.00001 to 0.0001 as a more reasonable threshold in many data situations.
- Improved robustness of 'cov_hall' by (i) first centering the curves before taking the cross product and smoothing it and by (ii) ensuring positive (semi-)definiteness of the covariance matrix with 'Matrix::nearPD'.
- Improved speed of 'cov_hall' for large data by using 'mgcv::bam' for smoothing.
- Added argument 'npc_varExplained' to functions 'fpca_gauss' and 'bfpca' to choose the number of FPCs based on the share of explained variation.
- All 'verbose' arguments now take values between 0-4 to better control the level of detail of info messages.
- A lot of minor fixes and refinements.
- Updated potentially invalid URLs
Preparing things below
- mgcv spline choices
- penalization for optimization (not sure how to choose best sigma)
