Create a data frame to assist with creating an observed bias plot
observed_bias_tbl(ps_mod, outcome_mod, drop_list = NULL)
ps_mod 
Model object for the propensity score model 
outcome_mod 
Model object for the outcome model 
drop_list 
Named list of covariates or groups of covariates to drop if

Data frame with the following columns:
dropped
: The covariate or group of covariates that were dropped
type
: Explanation of dropped
, whether it refers to a single covariate (covariate
) or a group of covariates (group
)
ps_formula
: The new formula for the updated propensity score model
outcome_formula
: The new formula for the updated outcome model
ps_model
: The new model object for the updated propensity score model
p
: The updated propensity score
ps_mod < glm(am ~ mpg + cyl + I(hp^2), data = mtcars) outcome_mod < lm(qsec ~ am + hp + disp + wt, data = mtcars) observed_bias_tbl( ps_mod, outcome_mod, drop_list = list( group_one = c("mpg", "hp"), group_two = c("cyl", "wt") ) )
