Derivation of normal distribution pdf
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 ... WebApr 11, 2024 · The droplet size distribution is log-normal. The above analysis suggests that the droplet size distribution may follow a log-normal distribution. The scaling ansatz of Eq. 2 for the SDF is equivalent to the following scaling for the probability density distribution (7) where f, the scaling function in Eq. 2, and F are related as follows (8)
