Towards the end of the Course, you will be working on a live project. You can choose any of the following as your Project work:

• Project #1: Sentiment Analysis of Twitter Data
  Industry: Social Media
  Description: A sports gear company is planning to brand themselves by putting their company logo on the jersey of an IPL team. We assume that any team which is more popular on twitter will give a good ROI. So, we evaluate two different teams of IPL based on their social media popularity and the team which is more popular on twitter will be chosen for brand endorsement. The data to be analyzed is streamed live from twitter and sentiment analysis is performed on the same. The final output involves a comparable visualization plot of both the teams, so that the clear winner can be seen. The following insights need to be calculated:
  • Setup connection with twitter using twitter package. And perform authentication using handshake function.
  • Import tweets from the official twitter handle of the two teams using SearchTwitter function.
  • Prepare a sentiment function in R, which will take the arguments and find its negative or positive score.
  • Score against each tweet should be calculated.
  • Compare the scores of both the teams and visualize it.
• Project #2: Census Data Analysis
  Industry: Government Dataset
  Description: Analyze the census data and predict whether the income exceeds $50K per year. Follow end to end modelling process involving:
  • Perform Exploratory Data Analysis and establish hypothesis of the data.
  • Test for Multi col-linearity, handle outliers and treat missing data.
  • Create training and validation data sets using Stratified Random Sampling (SRS) of data.
  • Fit Classification model on training set (Logistic Regression/Decision Tree)
  • Perform validation of the models (ROC curve, Confusion Matrix)
  • Evaluate and freeze the final model.
• Additional Resources:
  Here is the list of few additional case studies that you will get at edureka for deeper understanding of R applications.

  • Study#2: Strategic Customer Segmentation for Retail Business
    Industry: E-Commerce, Retail
    Description: In this case study, we will consider the dataset from a UK-based online retail business for the last two years. The objective of this case study is to do customer segmentation in this data set.
    For this exercise, we are going to use customer’s recency, frequency and monetary (RFM) values. From these three derived values, we will segment entire customer base and will generate insights on the data set provided to do customer segmentation using RFM Model based Clustering Analysis.
    Data-set: Comprises 0.5 million records and 8 variables. Each record is for one online order placed by the customer.
  • Study#3: Pricing Analytics and Price Elasticity
    Industry: Retail
    Description: A retailer is planning to sell a new type of cheese in some of its stores. This is a pilot project for the retailer & based on the data collected during this pilot phase, retailer wants to understand a few things.
    To promote sales of cheese, the retailer is planning for two different types of in-store advertisement:
    • Cheese as a natural product
    • Cheese as a family caring product

    Now the retailer wants to know:

    • Which in-store advertisement theme is better and giving better sales of cheese in the store?
    • How the sales of cheese is reacting to its price change i.e. price elasticity?
    • What is the impact of the price changes of other products in the same store (e.g. Ice-cream & Milk) on the sales of cheese i.e. cross-price elasticity.
    • What should be the best price of cheese to maximize the sales and then do sales forecast.

    Data-set: The data set used in this case study will have the following columns:

    • Price of Cheese
