In koohyun-kwon/rdadapt:

Standard Deviation Given Weights

Description

Calculate a standard deviation of a linear estimator given weights and conditional standard deviations.

Usage

sd_w(w_t, w_c, sigma_t, sigma_c)

Arguments

w_t	weights for treated observations.
w_c	weights for control observations.
sigma_t	conditional standard deviations for the treated.
sigma_c	conditional standard deviations for the control.

Value

a scalar value.

Examples

w_t <- rep(1/10, 10)
w_c <- rep(1/5, 5)
sigma_t <- rep(1/2, 10)
sigma_c <- rep(1/3, 5)
sd_w(w_t, w_c, sigma_t, sigma_c)
