ols: Ordinary Least Squares

Description

Computes the ordinary least squares coefficients.

Usage

ols(X, Y, return_se = FALSE)

Value

(list): A list containing the following:

theta

(vector): p-vector of ordinary least squares estimates of the coefficients.

se

(vector): If return_se == TRUE, return the p-vector of standard errors of the coefficients.

Arguments

X

(matrix): n x p matrix of covariates.

Y

(vector): p-vector of outcome values.

return_se

(bool, optional): Whether to return the standard errors of the coefficients.

Examples

n <- 1000

X <- rnorm(n, 1, 1)

Y <- X + rnorm(n, 0, 1)

ols(X, Y, return_se = TRUE)
