Extracted text: Let Yi denote the observed data point and Yi denote the predicted value. Suppose we are going to model- predict value using an equation of a straight line. That means ĝi = a + bx; Using "Least-square criteria", derive formulas for coefficients a and b. (Show every step in your derivation.) Show transcribed image text
