Version 0.2.5
osqp instead of
rosqp now that osqp works. cobalt
is back.Version 0.2.4
rosqp instead of
osqp due to package failure. Also removed reliance on
cobalt in favor of MatchIt for data. Both
changes are temporary.Version 0.2.3
The rosqp package is now osqp, and is
faster with fewer bugs.
If focal is set, the estimand is automatically
changed to "ATT". In the past, focal would be
ignored unless estimand = "ATT".
Fixed some bugs with processing formula inputs. In particular,
functions can be used inside lapply loops and nested
functions more gracefully.
Other bugs fixes and small changes.
Version 0.2.2
Version 0.2.1
Changed default min.w in
optweight.fit() and optweight.svy.fit() to
1E-8 from 0. This ensures all weights are nonzero, which can reduce bugs
in other functions that require nonzero weights (e.g,
summ() in jtools and svyglm() in
survey`).
Fixed warning that would occur when interactions were present in
the model formula in optweight().
optweights have been discovered to be invalid for longitudinal
treatments, so attempting to use optweight()or
optweight.fit() with longitudinal treatments will now
produce an error. This can be overridden by setting
force = TRUE, though this is not recommended until further
research is done.
Version 0.2.0
Added optweight.svy and associated methods and
functions for estimating survey weights using optimization. These
weights when applied to the sample will yield a sample whose covariate
means are equal (within a specified tolerance) to given target
values.
Minor changes to check.targets. It will now produce
the covariate means when the targets argument is empty and
will produce the previous empty output, a named vector of
NAs, when targets = NULL.
Changes to how dual variables are processed and displayed. Now,
each dual variable coming from optweight represents the
change in the objective function corresponding to a 1-unit change in
tols. The reported duals are the sum of all the duals
affected by the constraint, so you can now reliably predict the change
in the objective function from a change in tols (it was
obscured and error-prone previously). The distinction between targeting
duals and balance duals is maintained.
