Display dominance diagrams to make a visual comparison of the samplesWhat is the difference between a two-sample t-test and a z-test? Here are the differences between the two-sample t-test and z-test: The t-test is used to compare and analyze whether the means of two populations are di...
Deleted items statistics: Activate this option to calculate and display statistics on the comparison of each element to the scale composed of others. These statistics include the mean and variance of the scale if the element was deleted, the correlation between the element and the sum of others,...

Specialized computer programs which are used for collection, organization, analysis, interpretation and statistical presentation of data are known as statistical software. The two main statistical methodologies, which are used in data analysis in some of the proprietary statistical packages used in ...
Unit root test can show that the residues are distributed much closer to the normal law in comparison to basic quotes. The word "closer" reflects the fact that the residues have the average and dispersion depending on time, which leads to instability of regression equation ratios. Using the tr...
The technique of the analysis of variance requires the comparison of two variances and a test for the significance of the differences between the calculated variances. The larger variance is divided by the smaller variance to give the ‘F’ ratio. 6.10F=S12/S22 Tables are available, which ...
Regression analysis was carried out using the Data Analysis Tool Pack in Microsoft Excel. ANN-based predictive modeling was carried out using the shareware version of the neural network and multivariable statistical modeling software, NNMODEL (Version 1.4; Neural Fusion, NY, United States). The ...
chance. When an observation shows a weak relationship between two variables or has a small number of data points, it is said to be statistically insignificant. However, when there are more data points showing a more consistent relationship, that correlation is said to be statistically significant....
