WebFor simplicity, use the shorthand notation Mdl = regARIMA (p,D,q) to specify a regression model with ARIMA ( p, D, q) errors, where p, D, and q are nonnegative integers. Mdl … WebThe software sets Intercept to 0, but all other parameters in Mdl are NaN values by default.. Since Intercept is not a NaN, it is an equality constraint during estimation.In other words, if you pass Mdl and data into estimate, then estimate sets Intercept to 0 during estimation..
