Below are sample questions representative of the exercises included on this worksheet and related ALG2.178 Regression with Log Linear and Log Log Models skill assessments:

Problem 1Difficulty: Mastery

Wildflower Roasters tried two models for the same data (you are deciding which transformation gives the best regression fit). Model 1 (log-linear) has R2 = 0.973. Model 2 (log-log) has R2 = 0.757. (Both models used the same x and y data.) Which model is the better fit based on these results?

ANeither; you need a different model.

BEither model fits equally well.

Clog-log

Dlog-linear

Solution & Explanation:For the same data, the model with the larger R2 explains more variation in the transformed response and is typically considered the better fit. Here, log-linear.

Problem 2Difficulty: Mastery

Wildflower Cyclery collected data (you need a prediction from the best-fitting model). Two regressions were run: Model 1 (log-linear): ln(y) = 4.264 + 0.029x, R2 = 0.943 Model 2 (log-log): ln(y) = 3.902 + 1.941*ln(x), R2 = 0.851 Use the better-fitting model (higher R2) to predict y when x = 50. Round y to the nearest tenth ((same units as y)).

Solution & Explanation:Choose the model with the higher R² value, Model 1 (0.943). Then ln(y)=4.264 + 0.029(50)=5.714, so y=exp(5.714)≈303.1 in the same units as y.

Problem 3Difficulty: Mastery

Sierra Tech models y = wind force (in newtons) versus x = building height with: ln(y) = 4.159 + 1.564*ln(x) Which statement best interprets the slope 1.56?

Ay increases by 1.56 newtons when x doubles.

BA 1% increase in y is associated with about a 1.56% change in x.

CA 1% increase in x is associated with about a 1.56% change in y.

DA 1-unit increase in x is associated with about a 1.56% change in y.

Solution & Explanation:In a log-log regression ln(y)=a+b ln(x), b is an elasticity: percent change in y ≈ b*(percent change in x). So for a 1% increase in x, y changes by about b%.
