    Adding Gaussians

    Given two different Gaussians (two different means and standard deviations,) how do I add them together to make a single gaussian?

    The sum of two Gaussian distributions is Gaussian with mean \mu_1 + \mu_2 and variance \sigma_1^2 + \sigma_2^2. Assuming independence, that is.

    See
    Normal distribution - Wikipedia, the free encyclopedia
    under "Properties".
