registr 0.1.0

• Added a NEWS.md file to track changes to the package.

registr 1.0.0

• Preparing for first release to CRAN
• Added Erin McDonnell as an author

registr 1.1.0

• 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 2.0.0

• 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

registr 2.1.0

• 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)
