Nonlinear Least Squares

I have data on bond yields (192 time series observations with i = 1,2,..18 monthly maturities) and estimated the following code: ' Compute factor loadings across maturities vector(18) tau group fm for !i=1 to 18 if !i=1 then tau(!i)=1 else if !i<=9 then tau(!i)=(!i-1)*3 else if !i<=11 then tau(!i)=(...

Giannone-Lenza-Primiceri prior

Hello.
At the moment with EViews11, with the Giannone-Lenza-Primiceri prior, the available option is to optimize only lambda1 and lambda3? how to optimize the rest of the priors?

Re: normal wishart

Hi Gareth, Let me come back to this topic. On equation 44.22, page 807 of the Eviews11 manual to obtain the covariance terms of a normal wishart, how come the C1 hyperparameter is not found in the three equations? Should H_inverse of NW = C1*I (identity with dimension k), and not as presented in tha...

Re: normal wishart

Or, should i take the inverse of C3 to obtain prior variance of Mu1?

Re: normal wishart

C3 is the degrees of freedom parameter. Is that too high to be a prior variance for mu1?

Re: normal wishart

is it because of the H kronecker product Sigma for the prior in beta in equation (44.18)?

normal wishart

hello. when running a normal wishart bayesian var, why is it not possible anymore in EViews11 to set prior for Lambda1?

Duration of execution of commands in program file

Hello.
Is there a command in EViews for me to know how long does EViews completes the execution of the commands within a program file? Thank you.

Re: EViews Blog

Hi Gareth,

In the EViews blog, what was the maximum number of iterations used to optimize the hyperparameters in the estimation of the GLP prior?

Re: EViews Blog

If that is the case, how are the columns D differ from the columns labeled DC? When you say uses dummy observations, you are referring to both sum of coefficients and initial observations dummy variables?

Thanks.
