get_Yit

A function to calculate outcomes for units in a particular time period `tp` in a panel data setting (this function can also be used to recover covariates, etc. in the first period).

Usage

get_Yit(df, tp, idname, yname, tname)

Arguments

df

the data.frame used in the function

tp

The time period for which to get the outcome

idname

name of column that holds the unit id

yname

name of column containing the outcome (or other variable) for which to calculate its outcome in the immediate pre-treatment period

tname

name of column that holds the time period

Value

a vector of outcomes in period t, the vector will have the length nT (i.e., this is returned for each element in the panel, not for a particular period)
