The current study provides a Gaussian version used to test for the normal mixture hypothesis with a single mean and two distinct variances. We derive the Gaussian version for the model by associating its score function with the generalized Laguerre polynomial. The Gaussian version is analytical, so that it can be simulated to obtain the asymptotic critical values of the likelihood-ratio test.
