get_tau_vector: Generate a grid of treatment effect values to test

In hettx: Fisherian and Neymanian Methods for Detecting and Measuring Treatment Effect Variation

Generate a grid of treatment effect values to test

Description

Creates a sequence of tau values spanning a confidence interval around the estimated treatment effect, with oversampling near the point estimate.

Usage

get_tau_vector(
  Y,
  Z,
  X = NULL,
  gamma = 0.001,
  grid.size = 21,
  grid.gamma = 100 * gamma
)

Arguments

Y	Outcome vector.
Z	Treatment assignment vector (0/1).
X	Optional covariate matrix for regression-adjusted estimation.
gamma	Width of the confidence interval. Default is 0.001.
grid.size	Number of grid points. Default is 21.
grid.gamma	Controls oversampling density near the estimate. Default is 100*gamma.

Value

A numeric vector of tau values with attributes te.hat, te.se, and te.MOE.
