Econometrics
Preliminary / analysis-support econometrics: demand / elasticity analysis, regression-based econometric summary, policy-impact framing, time-series econometric review, market / price scenario comparison, and model-assumption / interpretation review. PRELIMINARY ONLY — not a substitute for a licensed / PhD-level econometrician, journal-grade causal inference, full panel-data econometrics (fixed/random effects, cluster-robust SE, GMM), or regulated economic / pricing / policy submissions.
Demand / Elasticity Analysis
StandardBivariate log–log OLS on {price, quantity} observations — indicative price-elasticity estimate with R² and Pearson correlation. Framing only; causal identification (IV / experiment / RCT) is NOT performed.
⏱ 3-6 minutes
Regression Econometric Summary
StandardPer-regressor univariate OLS framing (slope, intercept, correlation) on y ~ x_j. Multivariate coefficients, standard errors, and diagnostics are deliberately NOT computed here — export to a statistical environment for real estimation.
⏱ 3-6 minutes
Policy Impact Framing
StandardDesign-level policy-impact memo with a threat-to-validity checklist by approach (pre-post / DiD / RDD / IV / synthetic-control). No causal effect is estimated — this is an identification-strategy memo.
⏱ 3-6 minutes
Time-Series Econometric Review
StandardDescriptive profile (mean, variance, trend, ACF(1), split-mean stationarity heuristic, optional seasonal-lag ACF). Not a substitute for ADF / PP / KPSS tests, cointegration, or structural-break detection.
⏱ 3-6 minutes
Market Scenario Comparison
StandardConstant-elasticity linearised comparison of price / market scenarios vs baseline — reports ΔQty%, new revenue, and ΔRevenue% per scenario. Accurate only locally; competitor / capacity / regulatory responses are NOT modelled.
⏱ 3-6 minutes
Model Assumption Review
StandardCoverage checklist of required assumptions per model type (OLS / logit / probit / panel-FE / panel-RE / IV / DiD / ARIMA / VAR) vs declared diagnostics. Gaps reporting — not a certification.
