AlgeRian R users: Fatma Zohra Samiha

Fatma Zohra Samiha has recently graduated from the Ecole Nationale Supérieure de Statistique et d’Economie Appliquée ENSSEA. She has a master degree in applied economics. Currently, she’s looking for her first challenge.

I know that at ENSSEA, we teach mostly Eviews and SPSS, how did you come to use R ?

I was introduced to the R world thanks to our time series professor, madam Chaouech Saloua who asked us to use to make a forecast using R and another software of our choice. I suddenly felt in love with R, getting the required results with few lines of code was magical.

Nice ! did you use base R or a specific package to make your forecast ?

I used the forecast package which provides the great auto.arima() function.

What was your master research topic ?

My master thesis treated the Application of supervised machine learning models in order to predict customer churn at Djezzy company.

So, a machine learning subject, quite ambitious, which model did you implement ?

I benchmarked three algorithms: logistic regression, Linear Support Vector Machine and random forest. The best performance was reached by the linear SVM model.

I hope you’ll find your dream job very soon where you’ll apply your expertise in data analysis and machine learning.

Finally, do you have a message to the current ENSSEA students who might read this article ?

I would like to invite all the ENSSEA students to use R instead of the classical commercial softwares because according to me R reperesents the future of data analysis.

Well thank you very much Miss Samiha for sharing your R experience with us. I hope you’ll contribute with Miss Kamila Benadrouche to establish the first Algerian R-ladies group. Of course, people can contact you at
