Compute serial correlation LM (Lagrange multiplier) test.

Carries out Breusch-Godfrey Lagrange Multiplier (LM) tests for serial correlation in the estimation residuals from the default equation.

Syntax

auto(order, options)

You must specify the order of serial correlation for which you wish to test. You should specify the number of lags in parentheses after the auto keyword, followed by any additional options.

Options

prompt | Force the dialog to appear from within a program. |

p | Print output from the test. |

Examples

To regress OUTPUT on a constant, LABOR, and CAPITAL, and test for serial correlation of up to order four you may use the commands:

ls output c labor capital

auto(4)

The commands:

output(t) c:\result\artest.txt

equation eq1.ls cons c y y(-1)

auto(12, p)

perform a regression of CONS on a constant, Y and lagged Y, and test for serial correlation of up to order twelve. The first line redirects printed tables/text to the “Artest.TXT” file.
