WebbDraw random samples from a multivariate normal distribution. The multivariate normal, multinormal or Gaussian distribution is a generalization of the one-dimensional normal distribution to higher dimensions. Such a distribution is specified by its mean and covariance matrix. These parameters are analogous to the mean (average or “center ... WebbAn normal distribution has mean μ and variance σ 2. A normal distribution with μ=0 and σ=1 is called standard normal distribution. The cumulative distribution function (cdf) evaluated at x, is the probability that the random variable (X) will take a value less than or equal to x. The cdf of normal distribution is defined as:
