Quanta moves fast

Quanta Advanced

• A new Advanced tier adds eight analysis families: multilevel models (including ordinal), generalized linear mixed models, latent class and profile analysis, finite mixture models, survival analysis, mediation, moderation, and measurement invariance.
• Every Advanced result runs against the same validation discipline as the base app: an automated suite of over 500 checks against NIST reference datasets and published statistical standards.
• Available on the Mac App Store (version 1.2.1) and the direct download (version 0.9.92). $179 per year, includes everything in Quanta. Details on the pricing page.

Representation checks in Data Quality

• Missingness by group: see whether nonresponse falls evenly across groups before you trust an analysis. Differential nonresponse quietly changes who your results describe, and now it is visible on one card.
• Sample vs population: enter population benchmarks and Quanta tests your sample's composition against them, naming which groups are over- or under-represented.
• Grouped descriptives keep every group visible: groups under ten cases are flagged rather than collapsed, marked to be read descriptively, not inferentially.
• These ship in the base app, not the Advanced tier. Who your data represents is not a premium question.

Version 0.9.91

• SPSS import, done right: variable labels and value labels from your .sav file now show in the Data Map, and user-defined missing values (discrete codes and ranges) import as missing instead of data.
• Quanta detects .sav files damaged by a text-encoding conversion in transit and repairs them on import. Files other packages refuse now open.

Version 0.9.89

• Rename or delete variables in Prepare data: fix a name everywhere it appears, or remove a variable created in error, with one-step undo.
• Clearer ReliCheck Intelligence summaries.

Quanta on the Mac App Store

• ReliCheck Quanta is now on the Mac App Store, alongside the direct download.
• Apple .numbers files import directly, joining CSV, Excel, SPSS (.sav), and more.

Version 0.9.88

• Continued reporting and stability refinements.
• Guide and Notes tabs in the inspector: method guidance and your own notes beside every analysis.

Bayes factors, side by side

• JZS Bayes factors for t-tests, plus Bayes factors for correlation, regression, and one-way ANOVA, reported alongside the frequentist results.
• Quantify evidence for the null, not just against it.

The fast descriptives engine

• Descriptive statistics rebuilt on Apple’s vector hardware: one million rows summarized in about a tenth of a second.
• Parity-verified against the previous engine across the full test suite before shipping.

Statistics correctness audit

• A dedicated audit pass across factorial ANOVA, discriminant analysis, multiple imputation, and APA reporting.
• Numerical-safety hardening throughout the engine, all captured in the validation record.
