Statistical features

• Summary statistics, including averages, standard deviation, median, percentiles, etc.
• Tests for Normal distribution: chi-square test, Kolmogorov-Smirnov test, D'Agostino-Pearson test
• Histogram and cumulative frequency graphs with option of superimposed plot of the Normal distribution
• Normal plot
• Box-and-whisker plot
• Correlation, rank correlation (Spearman's rho and Kendall's tau), and scatter diagram
• Simple regression and scatter diagram with choice of 5 different equations for approximating curve (including parabola), residuals plot
• Stepwise Multiple regression
• Stepwise Logistic regression
• One sample t-test, independent samples t-test and paired samples tests
• Rank sum tests: Signed rank sum test (one sample), Mann-Whitney test (independent samples), Wilcoxon test (paired samples)
• Variance ratio test (F-test)
• One-way analysis of variance (ANOVA) with Student-Newman-Keuls (SNK) test for pairwise comparison of subgroups
• Two-way analysis of variance
• Kruskal-Wallis test
• Frequencies table, crosstabulation analysis, Chi-square test, Chi-square test for trend
• Tests on 2x2 tables: Fisher's exact test, McNemar test
• Frequencies bar charts
• Kaplan-Meier survival curve, logrank test for comparison of survival curves, hazard ratio, logrank test for trend
• Cox proportional-hazards regression
• Meta-analysis: odds ratio (random effects or fixed effects model - Mantel-Heinszel method); summary effects for continuous outcomes; Forest plot
• Reference interval (normal range)
• Analysis of Serial measurements with group comparison
• Bland & Altman plot for method comparison (bias plot) - repeatability
• Mountain plot
• Deming regression (method comparison)
• Passing & Bablok regression (method comparison)
• Inter-rater agreement: Kappa and Weighted Kappa
• Receiver Operating Characteristics (ROC) curve analysis, sensitivity and specificity (with 95% confidence interval), likelihood ratios, predictive values
• Comparison of up to 6 ROC curves (with pairwise comparison of the area under the ROC curves, with 95% confidence interval and P-value)
• Interactive dot diagram for selection of threshold values
• Significance of difference between means, percentages and between correlation coefficients
• Different data comparison graphs, lines, bars, error bars (1 SD, 2 SD, 1 SEM, 95% CI, percentile ranges, etc.)
• Multiple box-and-whisker plots
• Notched box-and-whisker plots for pairwise comparison of medians
• Dot and line diagram (ladder plot)
• Quality control chart
• Youden plot
• Comparison of proportions
• Odds ratio, relative risk
• Sampling: calculation of sample sizes
