Question 1

What happens to B0 and B1 (and their standard errors) when the DV is multiplied by 100?

Answer 1

B0 and its se-mulltiplied by 100

B1 and its se-multiplied by 100

Question 2

What happens to B0 and B1 (and their standard errors) when the IV is multiplied by 100?

Answer 2

B0-nothing

B1 and its se-divided by 100

Question 3

What happens to B0 and B1 (and their standard errors) when 100 is added to the IV?

Answer 3

B0 (but NOT its se)-add 100

B1-nothing

Question 4

How to interpret coefficient when neither y nor x is logged?

Answer 4

1-unit change in x leads to B1 unit change in y

Question 5

How to interpret B1 coefficient when x is logged, but y is not?

Answer 5

1% change in x leads to (B1/100) unit change in y

Question 6

How to interpret B1 coefficient when y is logged, but x is not?

Answer 6

1-unit change in x leads to 100*B1 % change in y

Question 7

How to interpret B1 coefficient when both x and y are logged?

Answer 7

1% change in x leads to B1 % change in y
