After running an simple linear regression between Y and X, the researcher suspected there was a non linear relationship between the two variables. They modified theil model and got the results shown above. (X2 is X2) What is the correct interpretation? d. Y decreases by 1.018 each time X increases by 1 and increases by 20.19 each time X2 increases by 1 . b. Y initially decreases by 1.018 for a unit increase in X but that decrease decreases by 20.19 for each unit increase in X. c. Y initially decreases by 2.036 for a unit increase in X but that decrease decreases by 20.19 for each unit increase in X. a. Y Initially increases by 2019 for a unit increase in X but that increase decreases by 2.036 for each unit increase in X
