The standard deviation of the trend associated with the high volatility regime is not significant (((sigma _{eta_{2}}^{2})).
Both standard deviations are significant and relatively higher than the others, whereas the standard deviation of the trend level ((sigma _{eta })) is statistically non-significant.
Taking this into consideration, two additional estimations were made which imposed, first, a restriction of nullity on the standard deviation of the trend and then, due to its non-significance, another restriction on the standard deviation of the measurement equation.
An additional estimation was carried out, which imposed a restriction of zero on the estimator of the standard deviation of the trend, and no major changes in the other estimators were found.
Regarding the estimates, the standard deviation of the trend in the highest variance regime ((sigma _{eta _{2}}^{2})) is significant, just as the probability of being in a low variance regime (α1).
When observing the estimators provided in Table 1, one finds that the significance of the standard deviation of the trend associated with the low volatility regime ((sigma _{eta _{1}}^{2})) is strongly rejected, as well as the standard deviation of the measurement equation ((sigma _{omega})).
The proportion of generation MPANs on a substation only affects the standard deviation of the annual trend R5 (Fig. 2).
On the other hand, the standard deviations of the trend and the slope during periods of high volatility ((sigma_{upsilon_2}^1)) are significant.
Assuming the same standard deviation of 0.044, analysis of the trend in cIMT across all three tertiles of ACR allows a range of ≥ 0.035 mm in mean cIMT to be detected across tertiles, and ≥ 0.022 mm between two tertiles.
Interestingly, it is noteworthy that a similar trend between standard deviation of particle size and the mass ratio of AgNO3 and PVP is also found.
