Currently I have a vector of values $x [v_1,\ldots,v_n]$. I can plot the 1d Gaussian by plotting each point $\exp(-(v_i - \mu)^2/(2\sigma^2))\sqrt{2\pi\sigma^2}\cdots$ This gives me a nice looking normal distribution.. However I am trying to graph two different classes and their respective Gaussian and want to show how their probabilities overlap an how difficult it may be to linearly separate them. I was thinking of using a 2d Gaussian to do this, but I am drawing a blank. The formulas I have been trying $\exp(-( (x_i - \mu_x)/(2\sigma_x^2) + (y_i - \mu_y)/(s\sigma_y^2) ))$ are not giving me the representation I wish.. Or maybe I am just plotting it incorrectly..
Any Ideas?
Thanks!
