Question
For example, with five equally spaced values of the controlled variable the coded values could be -2, -1, 0, +1, +2; with six values the coded measurements could be -5, -3, -1, +1, 3, 5. cass Use this technique to find the regression line in the following case. Output (1000 tons) 11.1 12.3 13-7 14.6 15.6 1960 1961 1962 1963 1964 Year Estimate the output of the company in 1965.

2. When the values of the controlled variable are equally spaced, the calculation of the regression line can be considerably simplified by coding the data in integers symmetrically about zero. When the values of the controlled variable sum to zero, the estimates of the regression coefficients are given by âo = ỳ, â₁ = [xi yi [x²
