... In this context, (or, in the time domain, l ) are no longer independent variables. They are treated like any of the other parameters: i.e. are assumed to be random variables to be estimated from the observations by fitting a model. ... The MIDAS TSA package contains just one such model, namely Fourier series (SINEFIT/TSA) . ... In the time domain, the most important parameters to be estimated from the data are the correlation length of and time lag between the input signals. ...
