E-values for the EValue dispatch family (extender) — morie_sensitivity

Native E-values for the EValue dispatch family (evalues.OLS, evalues.RR, evalues.OR, evalues.HR, evalues.MD); OLS and MD use the \(\exp(0.91 d \pm 1.78 se)\) interval. Pairs with e_value_rr / e_value_or / e_value_hr / e_value_d.

Usage

morie_sensitivity_evalue(
  estimate,
  se = NULL,
  sd = NULL,
  type = c("OLS", "RR", "OR", "HR", "MD"),
  rare = TRUE,
  true = NULL,
  ci_lower = NULL,
  ci_upper = NULL,
  ...
)

Arguments

estimate: Observed effect on the requested scale.
se: Standard error of estimate (used by "OLS" and "MD").
sd: Outcome standard deviation (required by "OLS").
type: One of "OLS" (default), "RR", "OR", "HR", "MD".
rare: Logical; only relevant for "OR" and "HR" (passed to EValue). Default TRUE (rare-outcome approximation).
true: Reference value on the appropriate scale (default 0 for OLS / MD, 1 for ratio scales).
ci_lower, ci_upper: Optional 95% CI on the same scale as estimate.
...: Unused.

Value

A list of class morie_sensitivity_evalue with estimate, e_value_point, e_value_ci, type, method, and raw (the point and CI E-values).
