In these notes, we describe multivariate Gaussians and some of their basic properties. 1 Relationship to univariate Gaussians Recall 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 ... In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation.

WebThe properties of Normal Distribution. A normal distribution is “bell shaped” and symmetrical about its mean (μ). 50% of the observation lie above the mean and 50% below it. The total area under the curve above the horizontal axis is 1. Different values of (σ) determine the degree of flatness or peakedness of the graphs of the distribution. http://users.stat.umn.edu/~helwig/notes/norm-Notes.pdf
