Thank you Éric!

Tha last consulting: Could you give me a example (or routine) to load my
data (the first mail)?

Best Regards

Re: [Scilab-users] Grocer / Markov Switching Model

2013-01-11 Thread ericdoblas
Hello Éric, 

I need only one step, because I was able to replicate your example.

I can load the data:

Dates;LnPBI
1993q1;12,2847456986185
1993q2;12,3961633542544
1993q3;12,3993569016157 .. so on.

Then, I used impexc2bd, and after that, I loaded .dat file. But, I can´t run
LnPBI.

Thank you!

Eric

[Scilab-users] Re-sampling data and making 2 vectors

(is not the complete data, is an example)
My problem is  data1 is longer than data2. With data 1 i have one value of
temperature each 3 seconds, meanwhile in data 2 I have one value of
temperature each half second. 
I have to cut the matrixes, they should have the same lenght (because I
need Data2-(Data1-mean(Data1)) , and starts at the comun hour. I dont know
how do it, Any suggest?

The format of the time is for example 072301 (07:23:01)

What if you change the comma in your file into a dot (the dot is the
decimal separator in Scilab)?

Éric.

PS:
1) if you use the file I have sent to you, then LPIB is equivalent to LnPBI
you want to load into Scilab
2) and log(GDP) too!

I just need the last step. When I run

I have

Re: [Scilab-users] Re-sampling data and making 2 vectors

2013-01-11 Thread CRETE Denis
Hello Christophe,

Regarding noise, I have the feeling that lsq_splin can do a better job than 
interp1, which just interpolates linearly in its default operation. However, 
smooth might be the best choice for this task.

Regarding intersect, I considered that the data provided were representative 
of the case study, and taking into account only EXACT correspondence would - in 
this particular case - not miss any data.

Cdlt
Denis
PS: last line should have been:
disp([v',Temp1,Temp2,Temp2-(Temp1-mean(Temp1))]);

Objet : Re: [Scilab-users] Re-sampling data and making 2 vectors

Hello Denis

 intersect(Data1(:,1))

with this solution, you loose the information.

 It is also possible to interpolate the values of Data2 for the time 
 values in Data1(:,1) with interp1

I'm not familiar with this function, and have a question about the way it 
works. I have the feeling that it creates polynomial arcs (splines) that goes 
through all the data points, am I right?

If yes, then it is sensitive to noise.

Is there a function that does a smoothing on several data points so you can 
reduce the noise?

Best regards

 Regarding noise, I have the feeling that lsq_splin can do a better job

The example in the description page looks good, I'll try to understand
what they exactly mean by breakpoints.
But the fact it performs regression is a good point imho.

 smooth might be the best choice for this task.

The example that is provided here for smoooth
http://help.scilab.org/docs/5.4.0/en_US/smooth.html
create a smooth line, that goes away from a mean value.

And using the same step for the function (i.e. replacing
0.1 by 10) also increases the amplitude.

Anyway, thanks for your advice.

Dear Sir,

 I am a scilab user since years (version 2.0) I recently have moved to scilab 
on a macbook and when I draw a plot, in order to change its properties, I get 
the following message of error:

ATTENZIONE: L'interfaccia Tcl/Tk non è installata

meaning that the Tcl/Tk interface is not installed.

What can I do to get rid of this problem?

Thank you very much, yours, Armando Pisani.

TcL/Tk cannot be run on Mac OSes.
AFAIK, the Graphical editor GED is being to be rewritten in Java,
in order to get ride of this limitation [1].
So, i am afraid that the solution is either to stay with Mac and be 
patient...

or to go back to Windows or Linux and use GED in it current TcL/Tk release.

Samuel is right. The new implementation should be available with Scilab
5.5.0.
