Changes in version 2026-10-10 Added - New method underlying_forecasts(). Changed - Correction in internal functions when filtering series with NA and the beginning and not and the end of the series. - For polynomial methods, default I/C ratio fixed to 3.5 (as in X-11 for H-13). - implicit_forecast() function renamed to implicit_forecasts(). - New JARS related to version 2.5.2. Changes in version 2025-04-24 Changed - New JARS related to version 2.3.0 Changes in version 2025-03-01 Added - New function polynomial_matrix() to create a matrix of polynomial terms. - New function mmsre_filter() to compute the general Proietti and Luati (2008) filter with extension for non symmetric filters and with Timeliness criterion. - New parameter to confint_filter() to specify if the variance should be estimated for each asymmetric filters (default) instead of using the variance associated the symmetric estimates. Changed - filter() correction when the length of the series equals the length of the filter. - confint_filter() uses by default a Student distribution instead of a Normal distribution. Changes in version 2024-07-12 Added - New functions to compute functions to compute diagnostics and goodness of fit of filtered series: cross validation (cv()) and cross validate estimate (cve()), leave-one-out cross validation estimate (loocve), CP statistic (cp()) and Rice's T statistics (rt()). - New function confint_filter() to compute confidence intervals for filtered series. - New function is.finite_filters(). - New parameter zero_as_na in cbind.moving_average, boolean indicating if trailing and leading zeros added to have a matrix form should be replaced by NA. Changed - cross_validation() function renamed to cve(), cross_validation() is now deprecated. - New JARS related to version 2.2.0 Changes in version 2024-04-18 Changed - Merge pull request #22 from rjdemetra/develop - New JARS related to version 2.1.0 Changes in version 2023-12-12 Changed - Merge pull request #12 from rjdemetra/develop - Merge pull request #11 from rjdemetra/main - New JARS related to version 2.0.0 Changes in version 2023-07-06 Added - Initial JARS related to version 1.0.0
