# Bivariate Lognormal Distribution

Is there a pdf for bivariate lognormal distribution? Suppose there are 2 random variable $X_1$ and $X_2$ with standard normal distribution, how would the pdf of a bivariate lognormal distribution look like?

Thanks!

If $X_1$, $X_2$ are normally distributed, why would you expect their joint distribution to be a bivariate lognormal distribution? – fgp Oct 19 '12 at 9:50
