ARIMA order issue - d should always be less than 1 #835

Closed VerticaDataScientist closed 1 year ago

VerticaDataScientist commented 1 year ago

For ARIMA model it doesn't accept d greater than 0

This code:

from verticapy.machine_learning.vertica.tsa import ARIMA, AR, ARMA, MA
model = ARIMA(name='arima',order = (2,1,2))
model.drop()
model.fit(input_relation=vdf,ts = 'Time',y='Value', test_relation=vdf_test)
pred = model.predict(vdf=vdf_test,ts='Time', y='Value')

gives this error: d

This is because you have the wrong Vertica version. ARIMA is available since 23.4
