Econometrics for Management Decision Making Training Course

Participants can assess whether available data is fit for a proposed econometric analysis.

• Cross-sectional, time-series and panel datasets matched to decision questions

• Sampling frames reviewed for coverage errors and selection bias risks

Participants can create an analysis-ready dataset and identify material data patterns.

• Variable coding conventions for dates, categories, currencies and identifiers
• Derived measures calculated for rates, margins, lags and growth
• Duplicate records, invalid values and inconsistent labels corrected systematically
• Frequency tables exposing category imbalance, rare events and coding errors

Participants can interpret sampling uncertainty and statistical evidence in management reports.

• Population parameters and sample statistics distinguished for management evidence

• Confidence intervals communicate plausible ranges around estimated business effects
• Hypothesis tests assess claims about averages, proportions and regression coefficients
• P-values interpreted alongside effect size, uncertainty and decision consequences
• Type I and Type II errors linked to approval decisions

Participants can estimate and interpret a simple regression model for a business outcome.

• Scatterplots examine linearity, unusual observations and plausible business mechanisms
• Ordinary least squares estimates relationships between one predictor and outcome
• Regression equations translated into operational and financial decision language
• Intercepts, slopes and fitted values interpreted within observed data ranges
• Residuals examined as unexplained variation requiring further investigation
• R-squared and root mean squared error assessed for explanatory usefulness

Participants can specify multiple regression models that account for relevant observed drivers.

• Control variables selected using decision logic and causal diagrams
• Multiple regression isolates conditional associations among business performance drivers
• Coefficient interpretation holds other included predictors constant mathematically
• Omitted-variable bias assessed through plausible missing confounders and mechanisms
• Standardised coefficients compared cautiously across differently scaled predictors
• Partial regression plots reveal conditional relationships and influential observations

Participants can model segments, policy changes and nonlinear relationships in regression.

• Dummy variables represent segments, regions, channels and policy periods
• Reference categories establish meaningful baselines for coefficient interpretation
• Interaction terms test whether effects differ by customer segment
• Quadratic terms model diminishing returns, capacity effects and curved relationships
• Logarithmic transformations interpret percentage changes in demand, income and costs
• Predicted values compare scenarios while holding selected factors constant

Participants can diagnose common regression problems and select appropriate corrective actions.

• Residual-versus-fitted plots assess linearity and changing error variance
• Heteroskedasticity tests identify non-constant variance in model residuals
• Heteroskedasticity-consistent standard errors correct inference under unequal variance
• Variance inflation factors identify problematic multicollinearity among predictors
• Cook's distance flags influential observations requiring source and sensitivity review
• Normal probability plots assess residual distribution for small-sample inference

Participants can assess whether a regression specification supports the intended business conclusion.

• Functional-form choices compared using theory, plots and prediction performance
• Nested models tested using F-tests for additional explanatory variables
• Information criteria compare non-nested specifications with differing predictor sets
• Confidence intervals prioritised over binary significance labels in management reporting
• Joint hypothesis tests evaluate groups of commercial or policy drivers
• Sensitivity analysis records how findings change under reasonable specifications

Participants can design a forecast process with credible baselines and evaluation measures.

• Forecast purpose defines horizon, granularity, update frequency and accuracy needs
• Naive, seasonal-naive and moving-average forecasts establish baseline performance
• Train, validation and test periods preserve realistic forecasting chronology
• Mean absolute error and RMSE compare forecast accuracy consistently
• Bias measures reveal persistent over-forecasting or under-forecasting tendencies
• Forecast intervals communicate uncertainty around expected demand, cash or volumes

Participants can estimate time-series regression models for operational and financial forecasts.

• Trend terms represent persistent directional movement in business series
• Seasonal dummy variables capture calendar effects in monthly data
• Lagged variables model delayed responses to price, marketing and policy
• Autocorrelation plots identify dependence between successive forecast errors
• Durbin-Watson statistics screen residuals for first-order serial correlation
• Dynamic regression combines external drivers with trend and seasonal effects

Participants can recognise non-stationary series and avoid misleading time-series conclusions.

• Stationarity assessed through plots, rolling statistics and unit-root tests
• Spurious regression risks arise when unrelated trending series appear correlated
• Differencing converts level series into period-to-period changes where appropriate
• Log differences approximate growth rates for revenue, volume and prices
• Structural breaks investigated after acquisitions, crises, policy changes or system migrations
• Forecast stability reviewed when historical relationships shift materially

Participants can distinguish causal claims from predictive associations and state required assumptions.

• Causal diagrams identify confounders, mediators, colliders and treatment pathways
• Selection bias explained through systematic differences between treated and untreated groups
• Potential outcomes define treatment effects at individual and group levels
• Confounding variables require measurement, control or alternative identification strategies
• Correlation claims rewritten to avoid unsupported causal recommendations
• Identification assumptions documented before estimating intervention effects

Participants can select and assess designs for estimating the effect of a business intervention.

• Randomised controlled trials assign treatments to reduce observed and unobserved confounding
• A/B tests define treatment, control, outcome metrics and assignment rules
• Power calculations inform sample requirements for detectable business effects
• Difference-in-differences compares changes between treated and comparison groups
• Parallel-trends assumptions tested using pre-intervention outcome patterns
• Regression discontinuity exploits decision thresholds for credible treatment comparisons

Participants can use panel data methods to analyse repeated entities over time.

• Panel structures track customers, branches, suppliers or projects across periods
• Fixed-effects models control for stable unobserved entity characteristics
• Within-entity variation identifies changes associated with changing predictors
• Time fixed effects account for shared shocks and calendar conditions
• Random-effects assumptions compared against fixed-effects requirements and business context
