Question: Following data transformation regression analysis results in the estimation equation
Following data transformation, regression analysis results in the estimation equation log ŷ = 3.15 + 0.473 log x1 +1 0.354 log x2. Trans form this equation to the equivalent multiplicative model with estimation equation ŷ = b0 x1b11x2b22. (The base of the logarithms is 10.)
