MedCalc
statistical software
MedCalc is a statistical software package designed for the biomedical sciences. The first version of MedCalc, for MS-DOS, was released in April 1993, then a Windows version in November 1996.
It has an integrated spreadsheet for data input and can import files in several formats (Excel, SPSS, CSV).
MedCalc includes basic parametric and non-parametric statistical procedures and graphs such as descriptive statistics, ANOVA, Mann–Whitney test, Wilcoxon test, χ2 test, correlation, linear as well as non-linear regression, logistic regression, and multivariate statistics.
Survival analysis includes Cox regression (Proportional hazards model) and Kaplan–Meier survival analysis.
Procedures for method evaluation and method comparison include ROC curve analysis, Bland–Altman plot, as well as Deming and Passing–Bablok regression.
The software also includes reference interval estimation, meta-analysis and sample size calculations.
Version 15.2 introduced a user-interface in English, Chinese (simplified and traditional), French, German, Italian, Japanese, Korean, Polish, Portuguese (Brazilian), Russian and Spanish.

Begin with the source’s own compact description: “MedCalc” is statistical software. The dossier treats that line as a proposition to test through MedCalc, statistical and software, not as a finished interpretation.
Why this record matters
The phrase “statistical software” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Jul 26, 2026. The linked authority identifier is Q4272521. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1993, 1996, 2003 and 1373.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
Three-step research path
- Establish the record: confirm the title “MedCalc”, its source revision and the description used here.
- Expand the search: follow MedCalc primary sources, MedCalc archive and MedCalc research across catalogues and specialist indexes.
- Test the account: compare the strongest cited source with the responsible institution’s current record and note any disagreement.
