ls.diag: Compute Diagnostics for lsfit Regression Results

Description

Computes basic statistics, including standard errors, t- and p-values for the regression coefficients.

Usage

ls.diag(ls.out)

Arguments

ls.out

Typically the result of lsfit()

Value

std.dev

The standard deviation of the errors, an estimate of \(\sigma\).

hat

diagonal entries \(h_{ii}\) of the hat matrix \(H\)

std.res

standardized residuals

stud.res

studentized residuals

cooks

Cook's distances

dfits

cov.scaled

Scaled covariance matrix of the coefficients

cov.unscaled

Unscaled covariance matrix of the coefficients
