Stata alternative · Mac & Windows

Your .dta files, without the do-file.

Stratum opens Stata’s own .dta directly — variable labels on the headers, value labels read as words — and then does the everyday work by point-and-click. Regression arrives with its diagnostics already in the report, charts are built from pickers instead of syntax, and the whole thing is a one-time $119 or $249.

A linear regression report in Stratum: the coefficients table with confidence intervals and VIF, and an Effect Tests table giving each term a joint F test with its GVIF
The diagnostics come with the model. Coefficients with confidence intervals and VIF, and an Effect Tests table giving each term a joint F with its GVIF — in the report, not requested one estat command at a time.
Four Stratum charts under one selection: a scatter with the Gentoo penguins at full strength and the rest dimmed, a Pareto of islands where only the Biscoe bar is part-shaded, a histogram with the heavier body-mass bins shaded, and a box plot where only the Gentoo box is part-filled
One selection, every chart. Select rows anywhere — the datasheet or any chart — and every other view highlights the same rows. There is no command for this; you just drag.
A best-subsets regression table in Stratum ranking candidate models, with columns for k, R-squared, adjusted R-squared, Mallows' Cp, AIC, BIC and RMSE
Which predictors belong. Candidate models ranked on a stated criterion — k, R², adjusted R², Mallows’ Cp, AIC, BIC and RMSE in one table.
A Stratum datasheet of property listings: text columns such as City and Neighborhood beside numeric columns for bedrooms, square footage, list price and days on market, each column typed and right-aligned where numeric
Typed on the way in. Columns arrive with their types already worked out and labels intact, so the first thing you do with a dataset is look at it rather than describe it.

Stata vs Stratum

A license by the year, or a license you own.

Stata

New single-user licenses are sold by the year, and the tier you need sets the number — StataCorp’s own order cart shows $995 for Stata/MP4 annual. Perpetual licenses do exist through student and upgrade routes, so check which you qualify for.

Five years, five bills — unless a perpetual license is open to you.

Stratum

Bought once. The version you buy keeps working forever, online or off, on Mac and Windows alike.

When to keep Stata

Stata is the standard for a reason, and this page is not going to pretend otherwise. If your work runs on panel data, survival analysis, mixed models, instrumental variables, time series or survey-weighted estimation, Stata does those and Stratum does not. Nothing here replaces them.

What Stratum replaces is the other half of the job — the descriptive statistics, the ANOVA, the regression with its diagnostics, the contingency tables, PCA, clustering, decision trees and the charts you have to produce at the end. That work does not need a command language, and it does not need an annual license. If it is most of what you do, or if you are the person on the team who opens the .dta someone else produced, this is a $249 answer instead of a yearly one.

What you get

Descriptive statistics and summary reports, two-sample and paired tests with their nonparametric equivalents, one- and two-way ANOVA and MANOVA with post-hoc comparisons, correlation matrices with confidence intervals, contingency tables with chi-square and a mosaic plot, and linear regression with confidence intervals, VIF, leverage, Cook’s D and best-subsets selection. Professional adds PCA and correspondence analysis, clustering, decision trees, random forests and boosted trees, and SPC control charts with process capability. Import your .dta, .sav, .csv, .xlsx or fixed-width ASCII and try it on your own data first.

Frequently asked questions

Can Stratum open my .dta files?

Yes — directly, with no export step. Variable labels come across on the column headers and value labels are read as words in the cells, so a coded Stata dataset arrives readable. SPSS .sav, Excel, CSV and fixed-width ASCII open the same way.

Do I have to learn a command language?

No. There is no do-file and nothing to script. Every analysis is chosen from a control bar, states its own settings, and reopens exactly as you left it. The diagnostics arrive in the same report as the model rather than being requested one command at a time.

Should I keep using Stata?

If your work is panel data, survival analysis, mixed models, instrumental variables, time series or survey-weighted estimation, Stata is the right tool and Stratum does not replace it. If it is descriptive statistics, ANOVA, regression with diagnostics, contingency tables, PCA, clustering, trees and charts, Stratum does that work for a one-time price.

Is it a subscription?

No — Stratum is a one-time purchase, Standard at $119 or Professional at $249, and the version you buy keeps working. You can upgrade from Standard to Professional later.
