## What does you suggest to find if it is a...

Sorry, in France we don't learn much statistitics during high school, some binomial, some Gauss law ..

i will obviously test once I get the datas different laws, including the continous Markov chain that you describe.

But more important, is to find if it exists a trend to increase ou decrease during these 6 years.

Last year, our head department said that we could stop this task, as (that's what he thought, he's retired now) we did such a good job in another place that near zero consultations per day were made in urgencies.

Actually, I see (and our new head department too) that we're rarely under 2-3 consultations per day (last 15 days, that was once only under 5 consultations asked, and twice 7 consultations)

Thus, what is your advice about the more powerful way (meaning the second order risk) to find if a trend exist ? 6x325 observations are something, but on the other hand a mean of 2 consultations per day will probably don't help..

Firendly yours,

## Markov chain...

I'm not sure to fully understand your reply, as I always believed that Markov chains were really hard to compute.

But obviously I will follow your answer, as it sounds as a perfect match, and if it is trivial to do with Maple..

Friendly yours,

## I find how to do !...

Sorry to bother you with silly questions, I found how to do :

gusen_d := DataFrame(gusen);

I'm really stupid.

Thanks again for your precious help.

## DataFrame and Excel...

Thanks again, DataFrame sounds exactly as a match with my Excel file.

I got my matrix with :

gusen := Import("C:\\documents nega\\fiche gusen octobre novembre 41 consommation coke fours.xlsm");

Does exist a method to create and import directly this Excel file in a DataFrame ?

This file has 28 lines, but I will soon have another file with 1800 lines to study (each line with the number or rather rare occurences, likely following a Poisson law) so it could be somewhat useful to import directly such a file..

Thanks for your help again, friendly yours.

## Many thanks...

Many thanks for your answers. I think that Excel can convert dates to a float.

Thus, I have now to convert the columns to vectors and do that each element of a vector is apparied do the another. Thx to you, I shoud be able to do that .. :-)
