Oracle Error Message
ORA-40255: specified priors or weights table has an incorrect schema
Reason for the Error
The priors or class weights table whose name is specified in in the settings does not have the prescribed schema. A priors table should have the schema (target_value, prior_probability) and a class weights table should have the schema (target_value, class_weight)
Solution
Modify the schema of the input priors or class weights table to match the ones provided above (also in the documentation).
