NettetIn this paper, we propose the panel-limited information maximum likelihood (PLIML) approach to dynamic panel structural equation models. It is a simple exten-sion of the limited information maximum likelihood (LIML) method, which was orig-inally developed by Anderson and Rubin (1949, 1950). We intend to apply the LIML NettetWhen R estimates the ARIMA model, it uses maximum likelihood estimation (MLE). This technique finds the values of the parameters which maximise the probability of obtaining the data that we have observed. For ARIMA models, MLE is similar to the least squares estimates that would be obtained by minimising T ∑ t=1ε2 t. ∑ t = 1 T ε t 2.
