deseats 1.1.3
deseats 1.1.2 (2026-03-16)
create.gain() and runDecomposition() are now deprecated and replaced
by create_gain() and run_decomposition().
select_bwidth(), deseats() and s_semiarma() now have an argument
inf_criterion that lets the user switch between "bic" (the default) and
"aic"; this selects the information criterion (BIC or AIC) to use for
the ARMA order selection wherever relevant within those functions.
select_bwidth(), deseats() and s_semiarma() now warn the user, when
an extremely small number of observations is being used, which makes
the bandwidth selection highly unreliable.
- some internal functions have been made more robust, so that they do not
throw an error under small numbers of observations; instead they warn
the user (see previous point) and fall back to certain minimum / maximum
settings that still work (but are unreliable).
- some defaults in
set_option() have been adjusted, namely order_poly = 3
instead of order_poly = 1 as well as boundary_method = "shorten" instead
of boundary_method = "extend".
- a vignette was added to the package that introduces readers to the basic
applications of the package with an example.
- the
animate() method for output of deseats() now also shows proper
results for the case with boundary_method = "shorten" in set_options().
- the
predict() method for S-Semi-ARMA models now allows for bias adjustment
of point forecasts via bias.adjust = TRUE, if expo = TRUE.
deseats 1.1.1 (2025-06-23)
- fixed a bug in the forecasting of seasonal semiparametric ARMA models, where for the
special case of an ARMA for the rest including a mean estimate the forecasting intervals
under the normality assumption where too large by exactly that mean estimate
- fixed an issue, probably due to some updates in
ggplot2, where in autoplotfor
forecasting objects the legend for multiple forecasting intervals was not displayed
correctly anymore
deseats 1.1.0 (2024-07-12)
- the argument
correction_factor in the functions deseats, s_semiarma and
select_bwidth is now set to FALSE by default.
- further arguments were added to
deseats, s_semiarma and select_bwidth to
allow for a fine-adjustments of the algorithm, when an ARMA model is assumed
as the error process.
- the functions
seasonplot and seasonplot_gg were added to allow for the
creation of seasonal plots.
- the faulty link in the manual to the
RcppArmadillo package was removed.
- the example in the documentation of
ts_conversion was adjusted to use file.path for the path to the temporary data file.
