Bonjour a tous, voilà j'ai un exercice a faire en econometrie sur le logiciel Gretl (dont je n'y comprend pas grand chose) ca serait sympa si l'un de vous pourrez me donnez un coup de main! Par contre l'exercice est en Anglais:

Open data/sample file/Ramanathan/early retirement and its determinants

A,
Specify the regression model that you would like to estimate! Label the dependent and
independent variables!

B,
What is your expectation of the effect of unemployment rate on early retirement and why?

C,
How do we calculate t-ratio, sum squared residuum and std error of regression? Explain them!

D,
How many significant explanatory variables do we have on 1%, 5% and 10% significance
level? Please explain the significant estimated parameters!

E,
What is the mean of unemployment rate? How much is the standard deviation? Explain these
definitions! (you can use Microsoft Excel)

F,
What does it mean that the adjusted R-squared is 0,653916?

G,
What happens to the estimated values if we drop out insignificant explanatory variables? Are
there relevant changes in our model? Compare these two models?

H,
Can you suggest any other variables which can be relevant in explaining early retirement?

I,
What is the estimated early retirement rate in the the state number 32 at 5% significance
level? What is the residuum?

J,
Explain the P-value (F)!

Merci beaucoup ca m'aiderai enormement!
