A supporting function for TS_AUTO_ARIMA and TS_AUTO_ARIMA_OUTLIER.
Returns a varbinary value that encodes the specified integer input elements as a logical array of values.
If you supply four integers and pass the result to TS_AUTO_ARIMA or TS_AUTO_ARIMA_OUTLIER, then TS_INT_ARRAY maps to method 3 of the (IMSLS_METHOD, int method) input argument of imsls_d_auto_arima in the IMSL libraries.
