Description

Multivariate linear regression.

Usage

multivreg(y, x, plot = TRUE, xnew = NULL)

Arguments

y

A matrix with the Eucldidean (continuous) data.

x

The predictor variable(s), they have to be continuous.

plot

Should a plot appear or not?

xnew

If you have new data use it, otherwise leave it NULL.

Value

A list including:

suma

A summary as produced by lm, which inlcudes the coefficients, their standard error, t-values, p-values.

r.squared

resid.out

A vector with number indicating which vectors are potential residual outliers.

x.leverage

A vector with number indicating which vectors are potential outliers in the predicto variables space.

out

A vector with number indicating which vectors are potential outliers in the residuals and in the predictor variables space.
