October 2017 - Gretl-devel - gretlml.univpm.it

by yinung＠Gmail

I just installed gretl 2017c under XP but found plotting did not work. It says that "d2d2.dll cannot be found." After googling, it seemed that this dll comes with direct2D and only works under win7 and higher with some MS's patches. It means that gretl does not support XP hereafter? Thanks Yi-Nung

c code question

by oleg_komashko＠ukr.net

Dear All, Is it possible to compile gretl at own pc with new c functions on Linux, e.g. Ubuntu? In the case of "yes" what one need to do besides supplying a function code into gretl source directory? Oleh

scatters - limit to 16 items

by Schaff, Frederik

Hi there, as with many of my requests/comments, this might be an odd one (or, very specific to what I am doing) and you may feel free to ignore it ;). I just encountered that the scatters command, via GUI and hansl, is limited to 16 time-series (a 4x4 layout). Most often that will be sufficient, but I actually wanted to take a few at 21 time-series this way. Anyway, a kind of "warning" msg that only the first 16 series are considered would be nice (or better even, a more flexible handling, allowing more than 16 series). Best Frederik

grab 'hurst' results in a script

by Sven Schreiber

Hi, a student alerted me to the fact that it currently seems impossible to save the output from the 'hurst' command into a variable for scripting use. The natural way would be a $-accessor I guess. In a meta ways this is related to feature request 101 (https://sourceforge.net/p/gretl/feature-requests/101/), which is about accessing the results from the vif command. thanks, sven

crash when trying Midas-compacting

by Sven Schreiber

Hi, attached is a monthly small dataset (with missings, if that matters). Trying to reduce the data frequency ("compacting") to quarterly in a Midas way ("separate series") gretl crashes every time. On Windows with snapshot Oct 3rd. Apart from that, a minor suggestion: In the data compacting window, the label "spread to separate series" (or similar, ad-hoc re-translated from German) might get an extra hint: "(Midas)". thanks, sven

A laud to numhess()

Dear All, A laud to numhess: <hansl> include a_eff.gfn # not uploaded version, since it requires 2017d open transport.gdt logit auto 0 dtime bl = $model exey(&bl) #including "logit" into exey() took 1 minute of coding!!! <hansl> output: logit elasticities on Pr(auto = 1): coefficient std. error z p-value ------------------------------------------------------ dtime -0.0373775 0.0205797 -1.816 0.0693 * <stata> use http://www.principlesofeconometrics.com/poe4/data/stata/transport.dta, clear logit auto dtime margins, eyex(dtime) atmeans ------------------------------------------------------------------------------ | Delta-method | ey/ex Std.

Small/Serious(?) issu with MPI na MS Windows

by Marcin Błażejowski

Hi, simple script: <hansl> set verbose off function void foo (void) printf "Value from node %d: %d\n", $mpirank, $mpirank+1 mpisend($mpirank+1, 0) end function mpi --send-functions # Call function foo() # Collect results if ($mpirank == 0) scalar Sum = 0 loop for i=0..$mpisize-1 --quiet Sum += mpirecv(i) endloop printf "\nSum of received values: %d\n", Sum endif end mpi </hansl> Above code runs on Linux with either OpenMPI or MPICH, but crashes on Windows with MS-MPI. The error code is: "DEADLOCK: attempting to send a message to the local process without a prior matching receiv". The problem is with sending an object (here: scalar) from root proces to itself. When we give 2 conditions: 1. we call foo() if $mpirank !=0, 2. we receive from all nodes except root, the code works. The question is if this is an isse related with MS-MPI or this is gretl specific? Regards, Marcin -- Marcin Błażejowski

gretl bug: ordered probit model

by Artur T.

Dear all, just by chance I've found a bug (at least realized using 4-day old git on ubuntu). When adding a lagged intercept to the ordered probit model, gretl gets captured in infinite computation (I would call this a 'crash'): <hansl> open ooballot -q smpl Status > 0 --restrict # works probit Vote 0 CPI # crashes (infinite computation) series const_1 = const(-1) probit Vote 0 const_1 CPI </hansl> Best, Artur

factorized Boxplot

by Ignacio Diaz-Emparanza

I just found this rare boxplot in the attachment. The help says that for each boxplot both whiskers should be of size 1.5 times the interquartile range, but I can see clearly that some of the lower whiskers are bigger than that ¿is it possible or is this a bug? -- Ignacio Díaz-Emparanza Vicedecano de Ordenación Académica y Postgrado Facultad de Economía y Empresa, UPV/EHU c/ Lehendakari Aguirre, 83 48015 Bilbao Tel(Decanato): 946013602 Tel(Despacho): 946013732

'end outfile' instead of 'outfile --close' ?

by Sven Schreiber

Hi, this is a trivial syntax question/request: Wouldn't it be natural to introduce 'end outfile', similar to all the other blocks with 'end'? (Perhaps also get some script indentation in the block, but that's a separate and maybe more controversial thing.) thanks, sven
