Math Midterm II

Question 1

How to take a derivative (i.e., how to find the slope of a curve) words

Answer 1

For terms with exponents, bring down the exponent and then subtract one from the exponent.

Question 2

To compute the slope of a logit and probit…

Answer 2

we must pick our values of X, and compute the slope at that point. Often, this is done at the mean value of X.

Question 3

The consequence of measurement error in the dependent variable is …

Answer 3

that there is less precision in the estimates of the coefficients (e.e., higher standard errors).

Question 4

A larger sample size can mitigate the problem of

Answer 4

of measurement error in the dependent variable (but that doesn’t help mitigate bias caused by measurement error in the independent variable. )
