Trended dispersion was used for significance testing.
We present the results in 5 subsections: global features of the surveillance system; frequency distributions; means, seasonality and trends; dispersion; and relationships between mean, variance, and skewness.
Dispersion was estimated across samples using the estimateGLMTagwiseDisp function in R (following estimateGLMTrendedDisp) such that estimates were squeezed toward the trended dispersion values with a prior degrees of freedom value of 20 (McCarthy et al. 2012).
The rounded effective read counts of each sample, extracted from eXpress, were analysed using a GLM trended dispersion with Pearson correlation with eight degrees of freedom and P = 0.05, and also taking the replica effect into account.
The distribution of confirmed H7N9 cases by week was also extracted by creating two SD ellipses (covering 95% of the points while calculating the SD of the x-coordinates and y-coordinates from the mean centre to define the axes of the ellipse) to summarise the spatial spread of confirmed H7N9 cases (central tendency, dispersion and directional trends).
Results show that the mass ratio does not change the trend of dispersion curves but larger mass ratio lowers corresponding frequency at a fixed wave number and may extend the frequency range for energy trapping.
As observed from the HOMO/LUMO, the trend of dispersion of isodensity was almost similar in all compounds.
When a part containing such defects in a higher amount of 5% in porosity, the part tended to have a low fatigue life with a narrow trend of dispersion, which suggests that the defects be so seriously detrimental to the fatigue life of the part even the statistical nature of fatigue life is defeated.
Initially a descriptive analysis of the variables was carried out with central trend and dispersion data.
Moreover, there is a trend towards dispersion in the number of chromosomes per cell, moving from LG to HG.
In the descriptive analysis, absolute frequency and 95% CIs were calculated for categorical variables, and central trend and dispersion measurements were used for quantitative variables.
