Their test is based on the Lagrangian multiplier (LM) test and can be readily computed using the OLS residuals. Due to its computational ease, the LM test is more attractive in practice ...

It makes use of the residuals from the model being considered in a regression analysis, and a test statistic is derived from these. The null hypothesis is that there is no serial correlation of any order up to p. Because the test is based on the idea of Lagrange multiplier testing, it is sometimes referred to as an LM test for serial correlation.
