What is another word for jet lag?
Jet lag a circadian rhythm that is out of sync with the day-night cycle of the destination, as well as the possibility of internal desynchronisation. Jet lag has been measured with simple analogue scales, but a study has shown that these are relatively blunt for assessing all the problems associated with jet lag. The Liverpool Jet Lag Questionnaire was developed to measure all the symptoms of jet lag at several times of day, and this dedicated measurement tool has been used to assess jet lag in athletes. Jet lag may require a change of three time zones or more to occur, though
Lag operator 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 where formula_12 and formula_13 respectively represent the lag polynomials and Polynomials of lag operators follow similar rules of multiplication and division as do numbers and polynomials of variables. For example, means the same thing as As with polynomials of variables, a polynomial in the lag operator can be divided by another one using polynomial long division. In general dividing one such polynomial by another, when each has a finite order (highest exponent), results in an infinite-order
