In tipr: Tipping Point Analyses

Adjust a regression coefficient using the partial R2 for an unmeasured confounder-exposure relationship and unmeasured confounder- outcome relationship

Description

This function wraps the sensemakr::adjusted_estimate() and sensemakr::adjusted_se() functions.

Usage

adjust_coef_with_r2(
  effect_observed,
  se,
  df,
  confounder_exposure_r2,
  confounder_outcome_r2,
  verbose = TRUE,
  alpha = 0.05,
  ...
)

Arguments

effect_observed	Numeric. Observed exposure - outcome effect from a regression model. This is the point estimate (beta coefficient)
se	Numeric. Standard error of the effect_observed in the previous parameter.
df	Numeric positive value. Residual degrees of freedom for the model used to estimate the observed exposure - outcome effect. This is the total number of observations minus the number of parameters estimated in your model. Often for models estimated with an intercept this is N - k - 1 where k is the number of predictors in the model.
confounder_exposure_r2	Numeric value between 0 and 1. The assumed partial R2 of the unobserved confounder with the exposure given the measured covariates.
confounder_outcome_r2	Numeric value between 0 and 1. The assumed partial R2 of the unobserved confounder with the outcome given the exposure and the measured covariates.
verbose	Logical. Indicates whether to print informative message. Default: TRUE
alpha	Significance level. Default = 0.05.
...	Optional arguments passed to the sensemakr::adjusted_estimate() function.

Value

A data frame.
