Common questions

Can bivariate Gaussian distributions be used with non-normal data?

Bivariate Gaussian distributions assume normality, but in practice, data often deviates from this assumption. To address this issue, researchers use transformations, robust methods, or non-parametric approaches to accommodate non-normality.

• Overfitting and underfitting

Interpretation involves understanding the mean vector, covariance matrix, and the implications for the relationship between the variables. This requires a combination of statistical knowledge and domain expertise.
