  • 1. Data Analysis CourseAnalysis Design Document (Version-1)Venkat Reddy
  • 2. Data Analysis Course•• Introduction to statistical data analysis• Descriptive statistics• Data exploration, validation & sanitization• Venkat Reddy Data Analysis Course Probability distributions examples and applications• Simple correlation and regression analysis• Multiple liner regression analysis• Logistic regression analysis• Testing of hypothesis• Clustering and decision trees• Time series analysis and forecasting• Credit Risk Model building-1 2• Credit Risk Model building-2
  • 3. Note• This presentation is just class notes. The course notes for Data Analysis Training is by written by me, as an aid for myself.• The best way to treat this is as a high-level summary; the actual session went more in depth and contained other Venkat Reddy Data Analysis Course information.• Most of this material was written as informal notes, not intended for publication• Please send questions/comments/corrections to venkat@trenwiseanalytics.com or 21.venkat@gmail.com• Please check my website for latest version of this document -Venkat Reddy 3
  • 4. Contents• Background, Objective & Scope• Understanding Data, Data Cleaning & Audit• Overall summary & Summary by various segments• Benchmark Analysis, Tracking basic metrics, KPIs Venkat Reddy Data Analysis Course• Control charts , trends & forecasting• Multivariate analysis & segmentation• Driver analysis 4
  • 5. In scope & Out of scope• Background• What is the objective of the project• What is in scope of the project?• Are there any data related issues which will make some Venkat Reddy Data Analysis Course analysis impossible, hence out of scope? 5
  • 6. Data exploration, Data validation &Data sanitization• Data exploration- Get a feel of the data• Data validation - Is the data precise?• Data Sanitization – What if there are some inaccuracies in the data Venkat Reddy Data Analysis Course • Missing Value Treatment • Outlier Treatment Identification & Treatment 6
  • 7. Overall summary & Summary by varioussegments• Descriptive analysis of objective variable• Descriptive statistics of other important variables• Univariate analysis of important fields• Data visualization of variables Venkat Reddy Data Analysis Course• Analysis across various segments or cuts of the population• Bivariate analysis & visualizations • Analysis with more than two variables • Frequencies, means etc., considering combination of variables • Correlations and simple regressions 7
  • 8. Benchmark Analysis, Trackingderived metrics & KPIs• Derived variables• Key processing indicators • Ratios & deviations etc.,• Comparison vs target & average Venkat Reddy Data Analysis Course• RAG- Red Green Amber charts and Dashboards 8
  • 9. Control charts & trends, forecasting• Tracking of important metrics over time• 1.5 s control charts• Time series forecasting of future vales Venkat Reddy Data Analysis Course 9
  • 10. Multivariate analysis & segmentation• Finding the groups or segments in the population that are behaving alike • Segments with respect to objective • Overall segments Venkat Reddy Data Analysis Course 10 Details later
  • 11. Driver analysis• Regression analysis for finding the most impacting drivers• Most influencing factors on the objective variable• Quantifying the impact of each factor & comparison of factors Venkat Reddy Data Analysis CourseDetails later 11
