Abstract: This chapter starts with regression concepts and assumptions and proceeds to simple regression methods, estimation, testing, prediction, and confidence intervals. Testing includes tests on R2, slope, and predictive ability. Types of more advanced regression methods to be met in ensuing chapters are explained. Next, correlation concepts, assumptions, and the coefficient estimates of Pearson and Spearman are examined. Correlation is related to regression. Confidence intervals on the coefficient and tests on one and two coefficients are addressed. The interpretation of a small but statistically significant correlation coefficient is discussed.
