Hi Glenn - if I have run a logistic form of a Tobit regression for the error term would I need to replace the code for @cnorm and @dnorm to @clogistic and @dlogistic respectively. This is likely to be a last question for a while. Regards, Boydb

Glenn - I did it all again from scratch and it worked this time for me. Apologies, thank you and again Merry Christmas - this stuff would be good for the next version of the guide if possible. Regards, Boyd

Glenn, Wow! Good you are at this code - for me an early Christmas present it is. You I must thank. It all worked but the adjustment factor is 0.531 rather than 0.451(conditional on hours being positive) or 0.645 (not condition on hours - people who do and don't work) as per Wooldridge 2000 p. 545? R...

Glenn - I am trying to compute the factor for adjusting the Tobit co-efficients so they can be interpreted as they can be for OLS. I am following Wooldridge (2000, p. 543): 'Equation (17.27) allows us to roughly compare OLS and Tobit estimates. The OLS coefficients are direct estimates of dE(y]x)/dx...

HI Glenn,

I have tried as you suggested and I get a series which I assume are cumulative probabilities for each forecast. What do I do wth this series in order to get the single number adjustment factor?

Regards,

Boyd

Thanks Glenn - I'll give that a crack. Are you are Star Wars fan? Regards, Boyd :)

Dear Glenn and Raupel, I am having a similar problem with estimating the factor to adjust my co-efficients for interpretation. I have read the user guide (esp. pp. 213 and 222) and used the Forecast command on the equation toolbar and chosen Series to forecast: Index and the index is automatically n...
