Hello everybody, How can I manually compute the AIC for a Gaussian Mixture Model, with 2 predictor variables and one response variable. The data is approximated by 3 gaussians. I use this ( estimated values already calculated):
Can anybody tell me what is wrong? Kind regards Joaquim

Your computation of RSS (Residual Sum of Squares) is incorrect. You could use something like:
res = realValues - estimatedValues
RSS = sum(res.^2)
Check the Residuals section under this link: Linear Regression
