Regression Analysis
• Jared Dean as quoted in Big Data, Data
Mining, and Machine Learning
– From my experience, regression is the most dominant
force in driving business decisions today. Regression
analysis has many useful characteristics; one is the easy
interpretation of results. Regression concepts are widely
understood, and the methodology is well developed
such that a well-tuned regression model by a skilled
practitioner can outperform many algorithms that are
gaining popularity from the machine learning discipline.
