vcov_hac() (Conley
spatial HAC variance for
recoverU()/recoverUplus() fits, with a
data-driven bandwidth), boot_spatial() (spatial block
bootstrap that re-runs the whole pipeline on resampled blocks), and
rand_test() (conditional randomization test for the sharp
null of no direct effect). The default i.i.d. standard error is
anticonservative under spatial dependence — these give wider,
better-calibrated intervals.
recoverU/recoverU+ fits now carry their
influence values."mle" Matérn recovery engine now fixes the
smoothness at nu = 0.5 (exponential) by default,
controlled by the new matern_nu argument of
recoverU() / recoverUplus(). The free
four-parameter fit is poorly identified on weak residual fields and
could send the smoothness estimate to a numerical boundary; pass
matern_nu = NULL for the previous behaviour. The
"geoR" engine is unchanged.bias_bound(): an estimated post-matching bias bound
for an idaps() fit (covariate, exposure and variogram-based
confounding terms), with a print() method.idaps(), daps(),
naive_ps()) gain a match_method argument:
"greedy" (default, as before) or "optimal", a
deterministic 1:1 assignment via clue::solve_LSAP() that
needs no seed.boot_spatial() and rand_test() restore the
caller’s random-number state when seed is supplied, as the
other estimators already do.simulate_spatial_causal() now defaults to
n = 150 (previously 250).idaps()
(distance-adjusted propensity score with interference) and
recoverUplus() (doubly robust with recovered spatial
confounder and neighbourhood exposure) estimators, together with the
naive_ps(), daps() and recoverU()
comparators.simulate_spatial_causal() generates data with joint
spatial confounding and interference; spatial_ate() runs
all estimators and collects the results.matern_method = "mle"),
with an optional geoR engine for faithful reproduction of
the report.These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
