In rd2d: Boundary Regression Discontinuity Designs

Summary Method for 2D Local Polynomial RD Estimation

Description

Summarizes estimation and bandwidth results from a 2D local polynomial regression discontinuity (RD) design, as produced by rd2d.

Usage

## S3 method for class 'rd2d'
summary(object, ...)

Arguments

object

An object of class rd2d, typically returned by rd2d.

...

Optional arguments. Supported options include: CBuniform: Logical. If TRUE, displays uniform confidence bands; if FALSE (default), displays pointwise confidence intervals. subset: Integer vector of indices of evaluation points to display. Defaults to all evaluation points. output: Character. Use "main" to display estimation results, or "bw" to display bandwidth information. Default is "main". sep_main: Integer vector of controlling the column widths of the output table when output = "main". Default is c(4, 7, 7, 7, 7, 7, 17). sep_bw: Integer vector of controlling the column widths of the output table when output = "bw". Default is c(4, rep(8,8)). WBATE: Integer vector of weights for aggregated average treatment effect (WBATE). Should have non-negative entries summing up to one. If provided, an extra row for WBATE is added to the output table. LBATE: Logical. If TRUE, an extra row for largest treatment effect (LBATE) is added to the output table.

Value

No return value. This function is called for its side effects: it prints a formatted summary of rd2d results.
