I can't find Bivariate normality for my data set.
Help, please.
The “regular” normal distribution has one random variable; A bivariate normal distribution is made up of two random variables with a given correlation. The two variables in a bivariate normal are both are normally distributed, and they have a normal distribution when both are added together.
Standard statistical packages (Python, R, MATLAB, Stata, E-views) will let you input the numbers and get the probabilities.
If you are using Excel, there are free add-ins available on the internet (https://www.real-statistics.com/free-download/real-statistics-resource-pack/)
