WebRecall that the density function of a univariate normal (or Gaussian) distribution is given by p(x;µ,σ2) = 1 √ 2πσ exp − 1 2σ2 (x−µ)2 Here, the argument of the exponential function, −1 2σ2(x−µ) 2, is a quadratic function of the variable x. Furthermore, the parabola points downwards, as the coefficient of the quadratic term is negative.
