Overview of Data Analysis
The Roles of Data and Predictive Analytics in Business
- Explain how predictive analytics can help in business strategy formulation.
- Distinguish structured from unstructured data
- Recognize questions pertaining to business strategy that may utilize (active) predictive analytics.
Reasoning with Data
- Explain how inductive reasoning can be used to evaluate an assumption.
- Explain an empirically testable conclusion
- Explain how inductive reasoning can be used to evaluate an assumption.
Reasoning from Sample to Population
- Explain the reasoning inherent in a confidence interval.
- Explain the reasoning inherent in a hypothesis test.
Linear Regression as a Fundamental Descriptive Tool
- Explain both intuitively and formally the formulas generating a regression line for a single treatment.
- Explain the difference between linear regression and a regression line.
Correlation vs. Causality in Regression Analysis
- How to calculate partial and semi-partial correlations.
- How to execute active prediction using regression analysis.
Advanced Methods for Establishing Causal Inference
- Explain how instrumental variables can improve causal inference in regression analysis.
- How execute two-stage least squares regression.
Prediction for a Dichotomous Variable
- Describe the linear probability model.
- Calculate marginal effects for logit and probit models.
Identification and Data Assessment
- Explain what it means for a variable’s effect to be identified in a model.
- Explain extrapolation and interpolation and how each inherently suffers from an identification problem.
- Distinguish between functional form assumptions and enhanced data coverage as remedies for identification problems stemming from extrapolation and interpolation.
- Differentiate between endogeneity and types of multicollinearity as identification problems due to variable co-movement.
- Articulate remedies for identification problems and inference challenges due to variable co-movement.
- Solve for the direction of bias in cases of variable co-movement.
