Over the last 20 years, I've developed a wide range of tasks about statistical models, including software development, model building and massive data catching and handling.
I'm specialized in bayesian models, both dynamic (ARIMA, VECAR, Bass diffusion) and static ones (Probit, Logit, Counting Regression) applied in multiple real world problems like sales forecasting, churning, pricing, quantitative marketing, macroeconomic and commodity forecasting, for dozens of medium and large enterprises in several sectors as telecom, finances, energy, mining, retailing or agriculture. There are some examples
