storeControl gains the update.mu arg. to optionally circumvent update… …s of the mean parameters to speed-up special case of (I)FA models with centred data. Minor fix to param="means" plots for uncentered (I)FA results & minor fixes to account for uncentered data in means updates also. Documentation updates for CRAN compliance.
bnpControl gains the args. "thresh" & "exchange", implementing the ex… …changeable/thresholded slice sampler of Fall & Barat (2014): these are experimental features (both args. default to FALSE, both force ind.slice to FALSE, & exchange forces IM.lab.sw to FALSE). Prepared CRAN release.
Added function rltrgamma() to help with left-truncated version of col… …umn shrinkage MGP prior parameters, which can now be invoked using the new 'truncated' argument (default: FALSE) to mgpControl(). exp_ltrgamma() also added for computing expected values of left-truncated (inverse) gammas, for checking within MGP_check(..., truncated=TRUE). Hidden functions .sim_deltaKT() and .sim_deltaPT() added for similar reasons. Minor fixes to adaptive Gibbs sampler for MIFA models when delta0g=TRUE. Minor fixes to returned attributes from MGP_check when invoked in vectorised fashion. CRAN release.
Extended G_calibrate to use the Rmpfr & gmp libaries, use the full th… …eoretical ranges for the uniroot intervals, and work when alpha=0. Major speed-up to G_expected when alpha=0. G_variance also computed more accurately and efficiently when alpha=0. Minor speed-up to G_priorDensity for non-zero discount. Minor .version_above() and ifelse fixes. Minor speed-ups to simulation of scores/loadings (via backsolve() improvement) and speed-ups to local/column/cluster shrinkage parameters (via pre-computation). Prepared CRAN release.
Fixed initialisation issues for univariate data sets. error.metrics=T… …RUE now works for univariate data sets. Prettier axis labels for first two plot.meth="zlabels" plots. Slight speed-ups for both varieties of slice sampler in IM(I)FA methods. Minor CRAN compliance edits and & tiny documentation edits. Added ORCID iDs to DESCRIPTION. doi fixes. CRAN 2.1.5 release.
Ensured matrixStats(>=0.53.1) & mclust(>=5.4) in Imports: and gmp(>=0… ….5-4) in Suggests:. Package startup message now includes a check for whether a newer version is available on CRAN. Cosmetic changes to G_priorDensity plots. Stricter checking of permissible alpha values with negative discount. Minor documentation edits. Fixes when plot.meth="density" and param="alpha" for fixed positive discount. mat2cols example edits. Updated Bayesian Analysis citation. Updated email address. Final CRAN edits.
Minor edits for compliance with R 4.0.0. Improved handling of suggest… …ed packages Rmpfr & gmp in G_expected, G_variance, and G_priorDensity. Minor speed-up to Procrustes when dilate=TRUE. summary.Results_IMIFA gains the printing-related argument "MAP". Minor fixes for negative discount (an experimental feature). Minor efficiency gain to slice sampler for IM(I)FA methods. Edited printed details when `plot.meth="zlabels"` with unsupplied `zlabels`.
Fixes & speed-ups to MIFA/OMIFA/IMIFA when ~some~ clusters have zero … …factors. Speed-ups to simulation of column-shrinkage parameters when ~some~ clusters are empty. Accounted for cluster-shrinkage parameters when the number of factors increases. Minor bug fix for padding scores when the maximum number of factors increases. Minor fixes due to base::matrix, immediate warnings, dependencies for some hidden functions. More fixes & time improvements due to latest Rfast v1.9.8 (.col/row_vars -> col/rowVars). G_expected & G_variance gain the argument "MPFR". Variable & cluster specific communalities now both returned by get_IMIFA_results. Minor speed-up to rDirichlet for the symmetric uniform case. Spell-checking of documentation & removal of methods package from Suggests.
