armax-auto option occasionally generates this error
by Tim Nall
Thanks to all for the replies. Will try to find TRAMO. meanwhile, the
armax-auto option occasionally generates this error:
? armax(4, 4, BOTH, null, 1, 1, 0, 1, 0)
BFGS: initial value of objective function is not finite
*** error in function armax, line 82

question about variance decomposition
by Leandro Zipitria
Dear all,
I want to made a variance decomposition analysis, that is to decompose the
variance into particular covariates. This models are hierarchical models.
Is any command in Gretl that does the same analysis as xtmixed in Stata, or
proc mixed in SAS?
Thanks

possible bug with sending data to R session
by oleg_komashko＠ukr.net
It seems, there is a bug in exporting data on starting R session from Gretl If start a R session with the attached file opened in Gretl variables l_gdpr_usa and gdpr3 are read as they should be. gdpr_usa[1] is 99547.54
gdpr3=gdpr_usa/1000 gdpr_usa is read in R as [1] 142 1 2 5 4 6 7 8 9 15 19 21 26 27 29 31 34 37 36 40 41 43 48 [24] 46 44 50 49 52 54 58 60 64 67 70 68 72 79 81 74 82 83 85 89 91 86 88 [47] 95 94 102 103 101 99 106 112 116 118 121 122 124 131 120 115 107 104 110 113 126 130 127 [70] 132 137 3 12 17 23 20 11 10 13 14 16 18 22 25 24 28 30 33 32 35 38 39 [93] 42 45 47 51 53 55 56 57 59 61 62 66 65 63 69 71 73 76 75 78 77 80 84 [116] 87 90 92 93 96 98 97 100 105 108 109 111 114 117 119 123 125 128 129 133 134 136 140 [139] 139 135 138 141 143 The original source is http://www.eurmacro.eu/macrodata/datamtrx.html ; the data was copy-pasted to the empty text file. Original header gdpr_usa
"millions of U.S. Dollars; 1990 prices"
1870 99547.54 was edited to year gdpr_usa 1870 99547.54
and the text file was imported If recode the data as cross-section gdpr3 is read well but gdpr_usa is read as factor instead of numeric if type as.numeric(gdpr_usa) we again get [1] 142 1 2 5 , etc.

Problems installing arima X13
by JOSE FRANCISCO PERLES RIBES
Dear list:
I have tried to install arima X13 on gretl 1.9.14 and Windows 7 (I have
tried both version x86 and 64 bytes).
After downloading and installing arima X13 I have modified the
configurations (preferences) of gretl to indicate it the new path as usual
C:\Program Files\x13...
However, when I run the arima X12 tab from menu GUI, the initial graph is
opened, but the ouptut window is completely white,...no output is printed...
So, arima X13 only runs from gretl console and not for GUI? and Somebody
has had the same problem???
Thanks in advance

Ok. Is there a way to use strsub() to add newline to a string?

That's by design. The two sister funtions/commands printf and sprintf
support ASCII control characters, simple assignment does not. If you need
to embed a newline or a tab into a string, use sprintf. For example:
<hansl>
sprintf a "%d\t%d", 3, 4
print a
</hansl>
That said, we are considering the idea to turn the sprintf command into a
function (this is already available in CVS and the snapshots), so perhaps
you may want to experiment with the new notation, which would be
scalar n = sprintf(a, "%d\t%d", 3, 4)
where n is the number of characters that "a" contains.

Questions about strings and string substitution
by Logan Kelly
Hello,
Question about strings and string substitution. Why does option 1 yield different output from option 2 (see below). I am using 1.9.14 on Win 7 64bit
hansel:
#option 1
s = "1\n2\n3\n"
printf "@s"
#option 2
printf "1\n2\n3\n"
OUTPUT:
gretl version 1.9.14
Current session: 2014-04-22 23:49
#option 1
? s = "1\n2\n3\n"
Replaced string s
? printf "@s"
1\n2\n3\n
#option 2
? printf "1\n2\n3\n"

Mahalanobis Distance - Execution Time
by GOO Creations
Hi,
I'm benchmarking the Mahalanobis distance to see how the accuracy and
execution time changes with an increasing sample size. As far as I
understand the algorithm the execution time should grow linearly as the
sample size increases. The weird thing is that the time grows linearly up
to (and including) 199 samples, but then suddenly has a drop at 200
samples. I've attached a graph to illustrate this.
I'm using it to do outlier detection. The time drops at 200 samples, but
the accuracy increases without a sudden drop.
Does anyone know why this happens?
