Simulation results on the detection performance of the proposed control chart, compared with some other competing methods show that it provides quite robust and satisfactory performance in various cases, including intercept shifts, slope shifts and standard deviation shifts.
Beech sprouting is common on upper slopes, possibly due to more erosion and root exposure, while seed regeneration is more common on lower slopes, and spatial patterns shift across slope positions accordingly (Takahashi et al. 2010).
Graphically, this happens when the contours of growth rate shift their slope, such that beyond a critical slope the solution 'jumps' to the other corner of the triangle.
Open image in new window Figure 2 ARL comparisons under βσ shift in slope with ρ = 0.1, 0.5, and 0.9.
From Table 3, under βσ shift in slope, while the autocorrelation is weak (ρ = 0.1), the proposed MCUSUM method uniformly performs better than MEWMA method.
Among these, 18 genes revealed a sharp shift in slope at some time-point within the first decade of life, mostly in the newborn period, as indicated by PAX8 (Fig. 2 and Figure S1).
PCs might be more complex in their interpretation in respect to hearing, but they enable representation of both overall threshold shift and slope of the audiogram.
In the third animal (Fernando), the model that best fit the data was one in which the fit to the three curves differed in both horizontal shift and slope.
If within-knob recombination occurred at levels similar to the flanking gene-rich areas, we would expect to see an upward shift in slope of the associated recombination curve (since most of the knob sequences are missing from the genome assembly).
Among women, none of the cohorts showed a substantial upward shift in slope in the log-mortality curves due to ischaemic heart disease around the time of menopause 45-55 yearss), and there was a log-linear increase in mortality throughout all ages.
