"NaN" value as output of the apollo_probabilities(apollo_beta, apollo_inputs, functionality="estimate")
Posted: 23 Jun 2022, 12:26
Hi Stephane and David,
I have created my simple linear MNL model for the SP dataset and it works properly. However, when I have tried to convert the utility functions (cost and time) to log MNL, I am getting "NaN" values in my results for the following function.
apollo_probabilities(apollo_beta, apollo_inputs, functionality="estimate")
I have tried to remove the NA values from my dataset using the following code
rawData = read.csv("df_output_avAlts.csv",header=TRUE)
database <- rawData # Duplicate data frame
database[database == "" | database == " "] <- 0 # Replace blank & space by 0
But still, I am getting the following error for the model function:
--------------------------
Testing likelihood function...
Apollo found a model component of type MNL without a componentName. The name was set to "MNL" by
default.
Error in apollo_validate(mnl_settings, modelType, functionality, apollo_inputs) :
Some utilities for model component "MNL" contain values that are not finite numbers!
--------------------------
I was wondering if you could guide me on this.
Best wishes,
Nima
