Statwise brings back the statistical analyses people used to run with the Analysis ToolPak, inside
Google Sheets™: pick a range, pick an analysis, and get a full labelled output table in a new tab.

WHERE TO FIND IT AFTER INSTALLING
Statwise opens in the SIDE PANEL on the right of your spreadsheet, not in the Extensions menu.
Look for its icon in the narrow strip down the right edge; if that strip is hidden, click the
small arrow at the bottom-right corner to show it.

TWELVE EVERYDAY ANALYSES ARE FREE
• Descriptive statistics · correlation · covariance · histogram · rank and percentile
• t-Test: two samples with unequal variances (Welch), with equal variances (pooled), and paired
• z-Test for two means · F-Test for two variances
• Moving average · exponential smoothing

BUILT FROM WHAT THE OLD TOOL GOT WRONG
• Nothing ever fails silently. Every run ends with a result or with a message naming the cause and the
  exact cell — for example "C47 contains text ('n/a')" — and offers to skip those cells and continue.
• Your sheet is never modified. Results always go into a new tab, and you stay on the tab you were on.
• No row ceiling for ordinary work: up to 500,000 cells are read at once, in a single pass, and the panel
  reports how many rows it analysed and how long it took.
• The unequal-variances t-test uses the Welch–Satterthwaite degrees of freedom — the formula SciPy and R
  use — and prints them, so you can check.

CORRECTNESS YOU CAN VERIFY
Regression is computed with a QR decomposition and reproduces the certified coefficients and standard
errors of the NIST Statistical Reference Datasets, including Longley — the dataset designed to break
implementations that take the numerically easy route. Every other statistic is checked against SciPy in an
automated suite that runs before each release. Correctness is not a paid feature: the same formulas run
for everyone.

PRO — $29 a year or $69 once, per user
• ANOVA: single factor · two-factor without replication · two-factor with replication
• Regression: one or many predictors, with standard errors, t statistics, p-values and 95%
  confidence intervals — the complete summary table, not just a slope
• Effect sizes with 95% confidence intervals: Cohen's d, Hedges' g, eta squared
• An APA-style sentence you can paste straight into a write-up
• Non-parametric tests: Mann-Whitney U, Wilcoxon signed-rank, Kruskal-Wallis, Spearman
• Chi-square goodness of fit and independence, with Cramér's V and a small-expected-count warning
• Assumption checks: Levene's test, variance inflation factors, Durbin-Watson
• Holm-adjusted pairwise comparisons after ANOVA
One licence per add-on. The key you buy here unlocks Pro in Statwise, on up to three Google accounts. A team licence covers every add-on we publish, for a whole organisation. If a licence lapses you keep every free feature.

FOR TEAMS AND ORGANISATIONS
If an administrator installed this for your whole domain, a per-person licence is the wrong shape.
A team licence covers everyone in the domain, for every tool we publish: $149 a year up to 50
people, $349 a year unlimited within one domain. It is invoiced, with your company details and VAT
number. Write to gheorghe.beschea@overheat.agency

PERMISSIONS
The only permission that touches your files is the narrowest one there is: "See, edit, create, and delete only
the specific Google Sheets™ spreadsheet this application is used in". Statwise cannot see your other spreadsheets,
your Google Drive™ or your mail. Every statistic is computed inside the add-on, and nothing from your spreadsheet
is sent anywhere. There is no analytics.

The second permission connects to an external service, and is used for exactly one thing: if you have a Pro
licence, Statwise asks our licence server once a day whether that key is still active. That request carries the
key and a random installation id — not your e-mail, and nothing from your spreadsheet. Without a licence key,
Statwise makes no network request at all. Details:
