The notation () indicates an autoregressive model of order p.The AR(p) model is defined as = = + where , …, are the parameters of the model, and is white noise. [1] [2] This can be equivalently written using the backshift operator B as
The notation ARMAX(p, q, b) refers to a model with p autoregressive terms, q moving average terms and b exogenous inputs terms. The last term is a linear combination of the last b terms of a known and external time series d t {\displaystyle d_{t}} .
Autoregressive model (AR) estimation, which assumes that the nth sample is correlated with the previous p samples. Moving-average model (MA) estimation, which assumes that the nth sample is correlated with noise terms in the previous p samples. Autoregressive moving-average (ARMA) estimation, which generalizes the AR and MA models.
Polynomials of the lag operator can be used, and this is a common notation for ARMA (autoregressive moving average) models. For example, = = = (=) specifies an AR(p) model.A polynomial of lag operators is called a lag polynomial so that, for example, the ARMA model can be concisely specified as

Of all the existing national television stations, the public broadcaster Radio Televizioni Shqiptar (RTSH) has the greatest reach: its signal covers 80.5% of the territory, followed by Top Channel with 79%, and TV Klan with 78%. However, there are also digital multiplexes but they are unaccounted for in the territorial reach figures.
DigitAlb Sh.A is an Albanian media, digital satellite and terrestrial TV platform based in Tirana, Albania. [1] [2] The TV platform began terrestrial broadcasts on 15 July 2004, and satellite broadcasts by the end of that year.
There are 12 TV channels in the first multiplexer and 11 radio channels. RTSH also runs a Satellite Multiplexer with 7 channels. RTSH 1 is the flagship generalist channel. RTSH 2 is dedicated niche communities, including cultural and ethnic minorities, broadcasting news editions in Greek, Montenegrin and Aromanian.
