e. Consider the following estimated OLS regression capturing the relationship between weight loss and distance walked (values in round brackets are the estimated t-statistics):
π€πππΜβπ‘ = β0.65 β 8.2 ln(π€πππ) + 0.35πππππππ (-9.028) (-3.04) (6.604)
π Μ 2 = 0.53
where weight is personβs weight in kilograms, walk is distance walked in km per day, calorie is number of calories consumed in thousands per day
i. Interpret the coefficient on ln(walk). Explain what can we capture by using ln(walk) in the model instead of just using walk.
