Description

A function to calculate the average outcome across all time periods separately for each unit in a panel data setting (this function can also be used to recover covariates, etc.).

Usage

get_Yibar(df, idname, yname)

Arguments

df	the data.frame used in the function
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

Examples

n <- 50
id <- rep(seq_len(n), each = 4)
t <- rep(1:4, n)
y <- rnorm(n * 4)
dta <- data.frame(id = id, t = t, y = y)
dta$Yibar <- get_Yibar(dta, idname = "id", yname = "y")
