In fect: Fixed Effects Counterfactuals

Calculate Cumulative Treatment Effects

Description

Calculate cumulative treatment effects

Usage

att.cumu(x, period = NULL, weighted = TRUE, alpha = 0.05, type = "on", plot = FALSE)

Arguments

x	a fect object.
period	a two-element numeric vector specifying the range of term during which treatment effects are to be accumulated. e.g. period = c(-1,1).
weighted	a logical flag specifying whether to calculate weigthed cumulative treatment effects based on counts at each period. Default is weighted = TRUE.
alpha	a numerical value that specfies significant level.
type	a string that specifies the type. Must be one of the following: "on" (switch-on treatment effect); "off" (switch-off treatment effect). Default is type = "on".
plot	A logical flag indicating whether to plot cumulative effects. Default is plot = FALSE.
