apollo_el {apollo} | R Documentation |
Calculates the probabilities of an exploded logit model and can also perform other operations based on the value of the functionality
argument.
The function calculates the probability of a ranking as a product of logit models with gradually reducing availability, where scale differences can be allowed for.

as follows.
"estimate": vector/matrix/array. Returns the probabilities for the chosen alternative for each observation.
"prediction": Not applicable.
"validate": Boolean. Returns TRUE if all tests are passed.
"zero_LL": vector/matrix/array. Returns the probability of the chosen alternative when all parameters are zero.
"conditionals": Same as "prediction".
"output": Same as "estimate" but also writes summary of choices into temporary file (later read by apollo_modelOutput
).
"raw": Same as "prediction".
