...oes a certain model in 3 ways: Vanilla NLS (using numerical differentation), Analytical derivatives (where the user supplies the derivatives) and analytical derivatives (using automatic differentiation). The three results agree, except for the correlation of parameter estimates : beta1 beta2 beta2 -0.1662 Numerical derivatives beta3 0.9145 -0.5407 beta2 -0.7950 Analytical derivatives beta3 0.9145 -0.9661 beta2 -0.1662 Automatic differentiation beta3 0.9145 -0.5407 Is this just a glitch of a small sample, o...

Hi, I conduct a panel data estimation and obtain estimators for two of the coefficients beta1 and beta2. R tells me the mean and covariance of the distribution of (beta1, beta2). Now I would like to find the distribution of the quotient beta1/beta2, and one way to do it is to simulate via the joint distribution (beta1, beta2), where both beta1 and beta2 follow t distribution. How could we genera...

Hi List, I was not able to make this work. I know it is a simple one, sorry to bother. Give me some hints pls. Thanks!
