Added Sample size calculation for Area Under the Precision-Recall curve.Added a shaded area option for the confidence interval of a Kaplan-Meier survival curve, ROC curve, Linear regression, Probit regression, Passing-Pablok regression and Bland-Altman plots (right-click on the confidence interval curve and select a fill color in the "Format." dialog box).Added transparency option for drawing objects (text box, rectangle, ellipse).Its extensive array of features make it a must-have tool for running method comparison studies and analyzing biomedical data. MedCalc requires at least basic statistics knowledge in order to get the most out of its potential.
It features outlier detection, correlation and regression tools, Bland & Altman plotting, while also enabling you to run Anova, variance ratio, mean, propertion, Chi-Square, Fisher and T-tests.Ī summary of the statistical report can be easily generated and data can be placed and viewed side-by-side thanks to the multiple comparison graphs function. MedCalc is capable of handling missing data, creating subgroups, calculating percentile ranks and power transformation. Up to 6 ROC curves can be compared, calculating the differences between the areas, the standard errors, P-values and more. It can generate the ROC curve graph with 95% confidence bounds, calculate specificity, sensitivity, predictive values for all the thresholds, likelihood ratios, generate conclusive plots and determine the size of an area under the ROC graph. One of the most important features of MedCalc is related to its ROC curve analysis capabilities. The built-in data browser offers a comfortable means of easily managing data, variables, notes, texts and graphs, while the array of supported graphs and diagrams (scatter plots, method comparison graphs, graphs for subgroups or for up to 24 continuous variables, survival curves, serial measurement, standardized mean plots and many more) make it perfect for analyzing trends and comparing information. The information can be easily sorted, filtered or edited. With an integrated spreadsheet with over 100,000 rows, MedCalc is capable of reading and displaying detailed data imported from Excel, SPSS, Dbase, Lotus or extracted from SYLK, DIF or text files. It provides the necessary tools and features for performing Receiver Operating Characteristic curve analysis, data plotting, Bablok and Deming regression and more. MedCalc is designed to meet the requirements of biomedical researchers with respect to the statistical analysis of large datasets. Statistical software for biomedical research with a rich set of functions, graph types and an advanced module for performing ROC graph analysis.
