Consider a binary response variable y and an
explanatory variable x. The following table contains the
parameter estimates of the linear probability model (LPM) and the
logit model, with the associated p-values shown in
parentheses.
Variable | LPM | Logit | |||
Constant | −0.69 | −6.30 | |||
(0.06 | ) | (0.06 | ) | ||
x | 0.06 | 0.21 | |||
(0.04 | ) | (0.06 | ) | ||
a. Test for the significance of the intercept and
the slope coefficients at the 5% level in both models.
b. What is the predicted probability implied by
the linear probability model for x = 20 and x =
36? (Round intermediate calculations to at least 4 decimal
places and final answers to 2 decimal places.)
c. What is the predicted probability implied by
the logit model for x = 20 and x = 36?
(Round intermediate calculations to at least 4 decimal
places and final answers to 2 decimal places.)
