Force time periods to be positive integers in
ptetools::setup_pte()
Fix bug related to accounting for variance of untreated group with continuous treatment
Added covid_data dataset (previously in
ppe); updated GitHub Actions workflows; fixed several
documentation issues; dropped tidyr dependency in favour of
data.table
Added pte_default(), a convenience wrapper combining
setup_pte(), two_by_two_subset(), and
pte_attgt() for standard DID/unconfoundedness-style
estimation
Added support for repeated cross-sectional data via
panel = FALSE, with a new
two_by_two_rcs_subset() subset function
Added print(), summary(),
autoplot(), and plot() methods for
pte_emp_boot (empirical bootstrap results)
Added aggte_fun argument to pte(),
panel_empirical_bootstrap(), and
qtt_empirical_bootstrap() for supplying a custom group-time
aggregation function on the empirical bootstrap path
Bumped minimum required BMisc version to 1.4.8 —
ptetools calls several BMisc functions
(add_cov_to_formula, rhs_vars,
combine_ecdfs, get_list_element,
weighted_combine_list) that were not available until that
version
