Description

Pre-test for time invariant effects of covariates in an interactive fixed effects model for untreated potential outcomes

Usage

cov_pre_test(
  yname,
  gname,
  tname,
  idname,
  data,
  nife,
  xformla = ~1,
  anticipation = 0
)

Arguments

yname	Name of outcome in data
gname	Name of group in data
tname	Name of time period in data
idname	Name of id in data
data	balanced panel data
nife	the number of interactive fixed effects to include in the model
xformla	Formula for which covariates to include in the model. Default is ~1.
anticipation	Number of periods that treatment is anticipated. Default is 0. This is in “periods”; e.g., code will work in time periods are equally spaced but 2 years apart. In this case, to allow for treatment anticipation of 2 year (<=> 1 period), set anticipation = 1.
