Hello, The result you're seeing is due to your use of nested loops. For each of the series named in the outer loop, i.e. "serie1", "serie2", and "serie3", you create three series in the inner loop, i.e. "d1", "d2", and "d3". Each of these s...

Hello,

Try these...

Hello,

Building on Gareth's example, a self-referential expression lets you maintain the previous dummy value in the case that the return is constant.

Certainly, with the appropriate downstream changes: %specs = "1 " + @str(!d-1) + " " + @str(!d) + " " + @str(!n) for %start %end {%specs} smpl %start %end ' Only needed if the 'list of instructions' includes operations affected by the sample for !i=%start to %end list o...

Hello, There are a couple of ways you could eliminate the redundancy in your program. You could move the common code to a subroutine, after which your program would look something like this: subroutine foo list of instructions endsub smpl {subp1} for !i=1 to !d-1 call foo next smpl {subp2} for !i=!d...

Hello, The new setting isn't in the documentation quite yet, but you can find it in the settings dialog: Options -> General Options -> Advanced system options -> "Reproducible random number sequences in series expressions". It's a global setting, not an option to 'rndseed' or another comma...

Hello, It appears that you're experiencing a "normal" EViews behavior involving random number generation. A sequence of random numbers generated as part of a series expression is dependent on both the state of the underlying random number generators (influenceable via the 'rndseed' command...

Hello, In a smpl statement, e.g. "smpl < start > < end >", the < start > specification uses the first observation within that specification while the < end > specification uses the last observation within that specification (this is only an issue when the specification as at a lower freque...

Hello, The existence of more efficient algorithms wouldn't surprise me, given the simplicity of the Fair-Taylor algorithm, but I haven't evaluated the algorithms bundled with the FRB/US model. I have no reason to doubt the authors, so exploring a native EViews implementation of their work in future ...

Hello, I don't see anything in your code that would specifically impair performance, there's simply a large number of iterations to be executed. In case you weren't already doing so, running the program in quiet mode may yield a modest performance improvement. Programs that execute a lot of individu...

Hello,

You can use nested calls to @pmax as a replacement for @rmax. For example,

Hello, The names "Shock1", "Shock2", etc., are hard-coded into the impulse response view, but with a little work you can recreate the response multigraph with your own labels. Since there isn't a way to alter individual graphs within a multigraph, the strategy must be to create a...

Hello, A few steps can help diagnose these sorts of issues. First is identifying the observation in question. If the critical observation isn't clear from the solution series, then it's frequently easiest to run the solution with the "Display detail messages..." option enabled on the "...

Hello,

It appears you want to reverse the vector. While EViews doesn't provide a reversing function, you can achieve the same result via other operations, e.g.,

Hello, There is an issue. When performing a stochastic solve, it appears that overrides may be ignored depending on the solution options (including the defaults, unfortunately). We should have a fix for this behavior ready for the next EViews patch. FYI, there's no need to specify a sample range as ...
