Dear All
I have a query about the appropriate type of error structure to specify in a
GLM. I have a response variable that is an ordered factor with 4 levels (0, 1,
2, 3). I also have continuous predictors which are abundances per cubic metre
(and are thus transformed counts). I would like to know which is the
appropriate error structure to specify for a GLM. I have looked at Venables and
Ripley (2002), but am not sure whether it is possible to use a Gaussian error
structure or which other error structure would be more appropriate. Thank you
in advance for your help. I am using S-Plus 6.0 Release 2 on Windows.
Yours sincerely
Anthony Richardson
