Hi All,
In estimation of an ordered choice model in Limdep the below command syntax only produces for me a summary of the Marginal effects and I would like to see the standard errors, p values etc as per output example in the manual.
ordered ;lhs=tec;rhs=z;marginal effects;table=ordered;cluster=firmnumb$
Any ideas on what i am doing wrong ??
Thanks

Subject: [Limdep Nlogit List] zero expenditures - Grouped data regression model
Dear Limdep user,
I've got another question concerning grouped data regression models (@Andreas: Thank you for your reaction to my previous question):
My dependent variable are expenditures (0€, < 100€, 100-200€, 200-400€, >400 €).
In a first model model I've collapsed the two first categories. So the first category (< 100€) included zero-expenditures.
However I've got the remark that these zero-expenditures should be a category on its own.
So my idea is to use
y=1 if y* < 0.1 €
y= 2 if 0.1€ ≤y* < 100 €
y= 3 if 100€ ≤y* < 200 €
y= 4 if 200€ ≤y* < 400 €
y= 5 if 400€ ≤y*
In my opinion it seems reasonable to assume that the latent variable y* can take negative values.
Is this straight forward, or are there better solutions to threat the zero-expenditures as a category on its own?
Many thanks,
Steven Vos
