The values for x1 should appear in the worksheet. The last window for ‘ Number of times to list the sequence’ can remain at 1. Enter 100 in the window labeled ‘ Number of times to list each value’. Highlight and select ‘x1’ for ‘ Store patterned data in’ window.Calc > Make Patterned Data > Simple Set of Numbers.These letters should be in the header above row 1 and directly below the default labels ‘C1’, ‘C2’, and ‘C3’. Start with a new worksheet, and create three columns: x1, x2, and phi.To plot a bivariate normal density for a given correlation value: You will need the formula that is found in the downloadable text file here: phi_equation_r=0.7.txt.

Proc g3d /*This plots in 3d the bivariate pdf for the variables x1, x2, and phi defined in the data set "a" above. And phi represents the value of the normal pdf as a function of both x1 and x2.*/ The domain is the square of values between -4 and 4 for both x1 and x2. %let r=0.9 /*This defines the macro variable r it will be referenced with &r throughout the code.*/ĭata a /*This data set defines the coordinates for plotting the bivariate normal pdf.
Title "Bivariate Normal Density" /*This sets a title that will appear on each page of the output until it's changed.*/ options ls=78 /*This sets the max number of lines per page to 78.*/

Note: In the upper right-hand corner of the code block you will have the option of copying ( ) the code to your clipboard or downloading ( ) the file to your computer. We have just two variables, \(X_\right)\) Here our understanding is facilitated by being able to draw pictures of what this distribution looks like. To further understand the multivariate normal distribution it is helpful to look at the bivariate normal distribution.
