Following data transformation, regression analysis results in the estimation equation log ŷ = – 0.179 + 0.140x. Transform this equation to the equivalent exponential model with estimation equation ŷ = b0b1x. (The base of the logarithms is 10.)
Answer to relevant QuestionsFollowing data transformation, regression analysis results in the estimation equation log ŷ = 3.15 + 0.473 log x1 +1 0.354 log x2.
