A normalized test statistic (Z-score) is used to check the statistical significance of the increasing or decreasing trend of mean precipitation and temperature values.
The χ2 test was applied to check the statistical significance of different variables.
One way ANOVA was carried out using SPSS (Statistical Package for Social Sciences) to check the statistical significance of the results.
To check the statistical significance of these results, we conduct the same exercise using the randomized data (i.e., the timing of the arrival of news is randomized).
In addition, to check the statistical accuracy of MODPEP, we have repeated the validating procedure by splitting the data set into training and test sets for 10 runs.
Thus we will perform realistic simulations in Section 3.2 and check the statistical character of stellar systems by comparing the results with the Hermite scheme, which is widely used in collisional stellar system simulations.
Parameters of the fitting of the cumulative scalar seismic moment curve (g) and the curve of the cumulative square root of the scalar moment (h, corresponding to the cumulative Benioff strain traditionally used in AMR studies), respectively, are shown in Table 1, to check the statistical significance of the accelerating/decelerating behavior.
With the second method, we check the statistical correlation between the domestic production of each commodity (i.e., the parameters used in the second step described above and reported in Figure 1), and both the industrial roundwood total production (IRW t ) and time.
To check the statistical significance of these results, we randomize the timing of the arrival of a news item and repeat the same exercises as in Figures 1 and 2. We then use the randomized data to calculate the mean and the standard deviation of the market activity measures.
For the parameters which could be obtained for every speaker in our corpus, (i.e., b_p and f_p y) durations), we concluded an analysis of variance (ANOVA) in order to check the statistical significance of differences between speakers based upon only one of these parameters at a time.
