Evaluating swine disease occurrence on farms using the state-space model based on meat inspection data: a time-series analysis

Table 2 Model parameters decided using the auto.arima function

Disease	Auto.arima	Drift	None zero mean
PA	(1,0,0)
Diaphragmitis	(0.1.1)		○
Enteritis	(0,1,1)		○
IH	(0,1,1)	○	○
MPS	(0,1,0)		○
Mycobacteriosis	(5,0,0)
PH	(0,1,2)		○
Pericarditis	(0,0,4)(1,1,0)		○
Perihepatitis	(0,1,4)(1,0,0)		○
Peritonitis	(0,1,1)	○	○
Pleuritis	(3,1,0)(0,0,1)		○

The table shows the order of the ARIMA model determined using auto.arima. Models with drift are circled in the Drift column, and models with non-zero mean residuals are circled in the non-zero mean column
PH, parasitic hepatitis; MPS, mycoplasmal pneumonia of swine; IH, interstitial hepatitis; PA, pulmonary abscess
