Problem with estimation of MDCNEV model
Posted: 03 Dec 2020, 12:38
I am currently working on an MDCNEV model but keep on getting the error message which reads -
Error in if (all(testL == 0)) stop("\nAll observations have zero probability at starting value for model component \"", :
missing value where TRUE/FALSE needed
Traceback---
3.
apollo_mdcnev(mdcnev_settings, functionality)
2.
apollo_probabilities(apollo_beta, apollo_inputs, functionality = "validate")
1.
apollo_estimate(apollo_beta, apollo_fixed, apollo_probabilities,
apollo_inputs)
I have tried the possible solutions suggested in Apollo website FAQs but those do not seem to work. Currently, I am working with the simplest possible specification of the model (=starting values) with alpha_base(=0), gamma for all modes(=1), delta for all modes(=1), sigma(=1), panel(=0), nesting coefficient theta (=0,1)
Let me know if anybody can help. Thanks in advance.
Best,
