First release.
epi2x2() builds a 2 x 2 table in standard
epidemiological orientation.risk_ratio(), odds_ratio() and
risk_difference() return the measure together with the full
worked derivation.attributable_fraction() computes the fraction among the
exposed or in the population, showing that the direct, Levin and
Miettinen formulas agree.epi_strata() and collapse_strata() handle
stratified data.mh_odds_ratio() and mh_risk_ratio() pool
across strata, printing the stratum weights and the crude estimate
alongside the adjusted one.homogeneity() implements the Breslow-Day test with
Tarone’s correction.check_work() compares a hand calculation against every
step of a derivation and reports where it diverged.steps_table() returns a derivation as a data
frame.options(epibyhand.verbose = ) and
options(epibyhand.digits = ).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.
