Re: 3D graphs

Well, technically I guess you could use Python or R. I'm sure they both allow creation of 3d charts.

If it does not have an "Optimize" checkbox next to it on the dialog, it cannot be optimized.

Re: normal wishart

Ah, that's a typo.

The first line should be C1, the second line should be C2 and the third should be C3. Apologies.

Re: sample every 30th observation from a series

Code: Select all

smpl if @mod(@trend,30)=28


This assumes that you have daily 7 data that starts on Jan 1st 1989. If the starting date is different, you'll have to change the "28" value. Just do:

Code: Select all

show @mod(@trend,30)

and see what the value is on 2020/07/15 and use that value in the sample.

Re: sample every 30th observation from a series

To be clear, you mean 7/15/2020, 6/15/2020 and 5/16/2020?

Oh, and what frequency is the workfile?

Re: last day of a month

I think I would build an index series, that resets to 100 on the first of the month, and compounds the daily returns, then compute the return based on the value of the index at the end of the month. Something like (and this is off the top of my head, so might need adjustment): series index = @recode...

Re: last day of a month

Re: normal wishart

Equations 44.18 through 44.22 have no lambdas. But in previous versions of EViews we abused notation by using lambda instead of C in 44.22.

Re: normal wishart

It doesn't exist in the Normal-Wishart prior. It is "replaced" by the C hyper parameters.
