استاد کے نوٹس
- Compare OLS, WLS, and Theil–Sen with or without an intercept to highlight how slope and tests respond to weighting or outliers.
- The step log records means, sums, coefficients, r/R², residual diagnostics, tests, ANOVA, and the LaTeX formula so students can follow each computation.
- The exported CSV includes x, y, w, fitted values, residuals, leverage, and Cook’s D for further analysis in spreadsheets.
عمومی سوالات
How is Weighted Least Squares implemented?
We recompute weighted means and covariances using w, derive the fitted line, and propagate weights to residual sums and Cook’s distance so diagnostics reflect the weighting scheme.
What does the قابلِ شیئر URL include?
The URL stores decimal, delimiter, estimator, intercept, and band options. Data is not embedded, so شیئر کریں the dataset separately when collaborating.
