The application of the method in the fitting of the best straight line or curve to a series of experimental results, with the aim of determining the relationship existing between two variables. The method is also used in finding the optimal solutions of systems of overdetermined linear equations.

The evaluation of the standard deviation of this quantity is done taking into account the so-called propagation of errors from the quantities that have been measured to the derived quantity.

Differential Scanning Calorimetry (DSC), Thermally Stimulated Depolarization Currents (TSDC) and Dielectric Relaxation Spectroscopy (DRS) were performed to probe the thermal transitions and the polymer molecular dynamics in these mixtures. The results show, that the mixtures are homogeneous in the whole temperature range studied for p-xylene contents c(px) < 0.20, whereas are partially crystallized for c(px). >= 0.20 (co-existence of homogeneous PEA/p-xylene phase and p-xylene crystallites). For 0.20 <= c(px) <= 0.30, the mixtures are partially crystallized only on heating (above the glass transition temperature, cold crystallization), while for c(px) > 0.30 during cooling. The partially crystallized mixtures exhibit a critical p-xylene content estimated at 0.12-0.15 that remains un-crystallized regardless of the p-xylene composition. The respective polymer glass transition temperature remains constant at -47 +/- 2 degrees C due to the presence of this specific amount of un-crystallized p-xylene for c(px) > 0.30, whereas it decreases significantly with increasing c(px). (0 < c(px) < 0.30). The alpha relaxation polymer segmental dynamics, related with the polymer glass transition, sustains its cooperative nature in the partially crystallized mixtures, whereas the distribution of a process relaxation times exhibit a slight broadening compared to the xerogel and homogeneous mixtures, ascribed to the spatial concentration fluctuations induced by the presence of p-xylene crystallites. Finally, the a process dielectric strength as well as the heat capacity increment of glass transition undergo significant depression compared to the homogeneous mixtures once the p-xylene crystallites are present.
