A workbench, not a spreadsheet

Statsflow is metadata-native from the ground up. It wraps best-in-class statistics with a survey-aware interface — built for studies of 1k–100k interviews and thousands of variables.

Lossless SPSS files

Read and write .sav and .zsav with complete metadata fidelity — variable and value labels, measurement levels, user-missing ranges, multi-response sets. CSV, Excel, Parquet, Stata and SAS too.

Weighted banner tables

Publication-grade cross-tabs with proper within-banner significance testing — column-proportions z-tests and Welch's t, computed on the Kish effective base.

19 statistical models

Linear, logistic, ordered and multinomial regression, factor analysis, PCA, CHAID, clustering, correspondence analysis, driver analysis, TURF and ANOVA — survey-weighted wherever the mathematics allows.

Native survey weighting

IPF raking, post-stratification and weight trimming built in, parity-tested against R's survey::rake. Effective sample size is surfaced everywhere it matters.

Local-first and private

Your data never leaves your Mac. No account, no cloud, no telemetry — open a file and start working.

AI interpretations

One click turns any model result into a plain-language write-up — what's significant, how strong the effect is, what to flag. Base-size aware, so it won't over-read a thin sample.

See it in action

Every surface is designed for survey data — value labels, weights and missing values are first-class, not afterthoughts.

Banner tables — weighted cross-tabs with within-banner sig testing and the effective base shown per cell.

Model results — summary diagnostics, coefficient tables and robust standard errors.

Driver analysis — importance decomposition with Shapley, relative weights and bootstrap CIs.

Explore — frequencies, descriptives and crossplots that respect value labels and missing values.
