Predictive Modeling

 Duration: 40 Hours         

                                                 The predictive modeling helps us to analyze the business intelligence and predict with confident what happening next few years so we can plan accordingly. Our course helps you to understand the concept of statistical technique and judge independently what you can do it for given data for given problem.

“Data is an information our job is to convert our data into meaningful information”.

(Note: the practical session for these concepts will be thought through R Tool)
