WebbJoint Probability Density Function for Bivariate Normal Distribution Substituting in the expressions for the determinant and the inverse of the variance-covariance matrix we obtain, after some simplification, the joint probability density function of (\(X_{1}\), \(X_{2}\)) for the bivariate normal distribution as shown below: WebbThe standard normal distribution is a normal distribution of standardized values called z-scores. A z-score is measured in units of the standard deviation. For example, if the mean of a normal distribution is five and the standard deviation is two, the value 11 is three standard deviations above (or to the right of) the mean.
