Hello,
I am currently doing an internship at Pfizer Incorporation, and the aim of this project is to measure the elasticity demand of Pfizer's products and to model the potential change in demand due to the different market factors (like price variation, marketing campaigns, reimbursement status, ...).
I do have statistical skills like data analysis, historical series, applied econometrics, analysis of variance and regression analysis. And I'm also familiar with R programming language.
I'd like to know how should I proceed the analysis ? like a plan of action that I can follow.
