splice_index()
now keeps names.
Fixed a bug with transmute_weights()
where the weights could be negative.
Price-index functions have better argument checking.
Updated maintainer email.
Added a parameter to generalize geks()
by controlling how indexes are
averaged over the rolling window.
Fixed a bug where transmute_weights()
and factor_weights()
could return
a result with a different length than w
.
Added a new function splice_index()
for splicing indexes calculated over
a rolling window (this was previously sketched in an example).
transmute_weights()
is now faster.
Bumped minimum version of R to at least 4.0.
The use of ...
in grouped()
and balanced()
is deprecated, and will be
removed in a future version. The same behavior can be had by using an
anonymous function.
Added the walsh_geks()
function.
back_period()
and base_period()
gain a new argument match_first
to
control whether products in the first period match to themselves or return NA
.
Updated documentation.
Added a brief vignette.
back_price()
and base_price()
have been removed.
Functions for transforming weights only keep the attributes of the weights (if any), as documented.
grouped()
no longer mangles names.
back_price()
and base_price()
are deprecated in favor of the more
general back_period()
and base_period()
functions. They will be removed in
a future version.
The algorithm for making GEKS indexes is now much faster with a rolling window.
The functions and overall structure of the package should be fairly stable from now on.
Added nested_transmute()
and nested_transmute2()
for transmuting the
weights for nested generalized means. To be consistent with argument names, the
first two arguments for nested_mean()
and nested_contributions*()
are
now r1
and r2
.
Added the geometric Theil and Rao indexes.
Added back_period()
and base_period()
, which are more general
than back_price()
and base_price()
.
Added lehr_index()
.
Fixed a rare warning about sqrt()
making NaNs in
generalized_logmean(-1)
when some inputs were close but not equal, despite
no NaN
s showing in the result.
The lm_index()
and *_agmean_index()
functions are now function factories.
Added the balanced()
operator to make it easier to remove NAs with price
index functions.
Added the geks()
function for using price-index function
(e.g., fisher_index()
) to makes a GEKS index.
Added French translations.
Made a number of optimizations to make the results
of generalized_mean()
, extended_mean()
, lehmer_mean()
,
transmute_weights()
, and factor_weights()
faster in common cases.
Added the grouped()
operator to make all functions work with grouped data.
Most function names have changed to be less awkward;
e.g., mean_generalized()
is now generalized_mean()
,
and contributions_geometric()
is now geometric_contributions()
. This is
unfortunately not backwards compatible, but needed to be done.
Added the nested_mean()
function to calculate nested generalized means
for, e.g., the Fisher index.
The interface for nested_contributions()
is now much simpler, and the
function is focused on making contributions for Fisher indexes. Added
the nested_contributions2()
function that implements a different algorithm.
Added the arithmetic_agmean_index()
and geometric_agmean_index()
functions
to calculate the AG mean index.
Added some functions for standard outlier-detection methods for price relatives.
Dropped the scale
argument for generalized_mean()
, as it really wasn't
needed and had the potential to make more problems than it solved.
