It is remarkable that optimal parameters always satisfy the condition of limited variance increase.
The average relative variance increase (RVI) due to nonresponse is small: 0.0407.
While the minimum value of the variance increase with water depth and the floating vessel top displacement, and decrease with riser wall thickness.
Furthermore, we show that the noise process has a global spatial distribution and that the variance increase is multiplicative rather than additive.
When the SCR decrease, the phase PDF of second hypothesis may migrate from to zero phase line with variance increase, which are shown in Figure 2(a).
Obviously, the unwrapped phase is biased, and both the bias and the variance increase with the frequency due to the accumulation of ±2π errors.
They are the average relative variance increase (RVI), the largest fraction of missing information (FMI), and the degrees of freedom (DF).s.s
The proposed approach uses a Markov chain approach to compute the statistical performance, and uses a statistical design model to design DSVSI ¯¯¯X and s charts for detecting the mean shift and variance increase.
Computational study indicates that optimal sample sizes decrease as the magnitudes of shifts in mean and/or variance increase, and higher values of quality loss coefficient lead to shorter sampling intervals.
By contrast, a prominent 5-day-long variance increase at JRSC (May 6 May 10, 2014), which was not observed in the FRN data, strongly suggested a local and most likely anthropogenic source.
The results of the simulation study show to what extent the bullwhip effect and the inventory variance increase and amplify when a periodic review order-up-to level policy applies, noting that more benefits generate when coordination starts at downstream echelons.
