tal functions. The Gaussian probability distribution with mean and standard deviation ˙ is a normalized Gaussian function of the form G(x) = 1 p 2ˇ˙ e (x )2=(2˙2) (1.1) where G(x), as shown in the plot below, gives the probability that a variate with a Gaussian distribution takes on a value in the range [x;x+ dx]. Statisticians commonly ...
