FactorLens

Turn a small numeric dataset into an explanation you can inspect and a forecast you can understand. FactorLens is built for business users, students, and researchers who want rigorous multifactor analysis without sending data to a server. Start with the guided Beginner Mode, then type observations, paste a spreadsheet table, or import CSV/TSV. Analyze up to 10 numeric factors and 1,000 rows directly on your iPhone or iPad. EXPLAIN THE RESULT • Multiple linear regression estimates each factor's association with the outcome while holding the other factors constant. • Standardized effects make factors easier to compare. • Exact Shapley/LMG importance fairly distributes the model's explained variance across correlated factors. • Confidence intervals and p-values keep uncertainty visible. CHECK THE MODEL • Residual and Q-Q charts reveal patterns and unusual distributions. • VIF and…
