Introduction la Tunisie vivait une situation économique très difficile depuis une période de 5 ans,  chaque fois qu’on croit toucher le fond, les choses empirent davantage. Un dinar en chute libre, des exportations en recul et des investissements qui n'avancent plus : c'est le constat global établi depuis 2011. Nous allons essayer dans cet article de détailler quelques chiffres clés afin de donner une image plus consistante et plus claire sur l’état des lieux de l'économie Tunisienne.

La Tunisie avait toujours le label du "petit" pays, avec peu de ressources et de moyens. Ce label était une sorte d'excuse ou d'argument pour justifier la lenteur du développement du pays et les difficultés rencontrées lors de la mise en place des programmes d'amélioration dans tous les secteurs. Mais ce n'est pas VRAI, la Tunisie n'est pas un petit pays, sa superficie est supérieure à ces pays : Autriche, Émirats arabes unis, Irlande ,Denmark, Pays-Bas, Suisse, Kuwait.. Nous avons plus de ressources humaines que ces pays: Belgique, Autriche, Suisse,Émirats arabes unis, Finlande,Norvège,Luxembourg..

So I have been on the panel of the Tv show Called " The Expert ", aired on  Tounesna Tv. The show is mainly a show about the economy worldwide, but it talks about the Tunisian economy and the main events that happened in the financial world.

As I have mentioned before, I have started giving a workshop at the Higher School of Statistics and Data Analysis; The subject is the economic and statistical analysis of the Tunisian Economy. I share here this week's requirements. Hello Team, I hope you are getting excited to start working with the Data! Starting from this week, we will not have the usual presentations, as this methods seems to be a time-waster. I will look at each group's work individually and have a workshop-methodology in reviewing your work each week. (this does not mean that you are not required to present your work! I expect the same quality and format of presentations each week, and you all have to be present at the class and work on your data  and show me the problems you have if there are any)

As I have mentioned in a previous post, I will be giving a couple of statistical workshops and courses at the Higher School of Statistics and Data Analysis of Tunis this year. The second course I am giving is about Market Analysis and Customer Segmentation Using Machine Learning Algorithms. Bellow the project description and some details about the goal of the work we will do this year.

Following the Statistical Analysis Software course I gave in the first semester of this year, I have started giving a couple of classes to freshman and sophomore statisticians . The first course is a statistical workshop during the second semester that will be focused on economical and statistical analysis of the Tunisian Economy.

In Tunisia, it's not the banks that finance the economy... It's the economy that finances the banks. This is what we call a dysfunctional system that will lead to a crisis sooner or later.
