To create a 2 D Gaussian array using the Numpy python module. My rule of thumb is to use $5\sigma$ and be sure to have an odd size. A reasonably fast approach is to note that the Gaussian is separable, so you can calculate the 1D gaussian for x and y and then take the outer p...
F-Graph calculates and plots the standard normal distribution frequency and density functions. One tail, middle, two tail and cumulative density functions (probabilities) can be calculated together with the raw frequency function. You may enter directly Z values referred to N(0,1), or X values ...

In the following, we will first give a bit explanation about the general setup and data distribution in the first section. Then we explain the theorems about the performance of the algorithm. Finally, we test the algorithm performance by generating data from the mixture of Gaussian Distribution ...
A random variable X is called Gaussian if its distribution density with respect to the Lebesgue measure is given by x↦pXx=1σ2πexp−x−m22σ2, where m and σ denote two constants such that m∈ℝ and σ > 0. In this case, we use the notation X~Nmσ2. In the particular ...
