Dear All:
I'm running an ordered probit in Zelig:
"totfb.probit <- zelig(as.factor(combined_rating) ~ tot_fb_threeyravg +
lim_go + ln_pop + ln_pci + pc_tax_effort + pc_debt,
model = "oprobit",
data = slack)"
I encounter the following error message:
"Error in svd(X) : infinite or missing values in 'x'"
There are no missing data or infinite values in the dataset, and the
model converges when I run it on sub-samples of the data. Is there a
chance that certain vectors are too large to compute the singular value
decomposition? If so, is there a solution? If something else is wrong,
how can I fix it? Thank you.
Sincerely,
--
