I’m very interested in machine learning, big data analytics and data mining. My expertise area in exploring, manipulating and visualizing data to find new patterns and signals, building statistical and quantitative models (e.g., regression, classification, clustering) with tools such as R Programming Language, Excel, Tableau, IBM SPSS Statistics,etc. In my current job, I m spending most of my time by building Marketing Mix Modelling in R and Excel .I m also creating interactive dashboards with using Rshiny and Tableau Marketing Mix Modelling is statistical analysis such as multivariate regressions on different KPIs such as sales, website visits, etc. and marketing time series data to estimate the impact of various marketing tactics (marketing mix). We isolate media effect from other factors and create a formula so that we can calculate contribution of each variable.
