  • A. Extrapolation, Interpolation, and Smoothing of Stationary Time Series
    "Extrapolation, Interpolation, and Smoothing of Stationary Time Series" is a foundational mathematical work by Norbert Wiener that developed the theory of optimal prediction and filtering for stationary stochastic processes, laying the groundwork for modern signal processing and control theory.
  • B. Frisch–Waugh–Lovell theorem
    The Frisch–Waugh–Lovell theorem is a fundamental result in econometrics that shows how the coefficients of a multiple linear regression can be obtained by first partialling out (regressing out) other explanatory variables.
  • C. Statistical Testing of Business-Cycle Theories
    "Statistical Testing of Business-Cycle Theories" is an econometric work that rigorously evaluates and compares competing explanations of business cycles using quantitative data and formal statistical methods.
  • D. Econometric Model of the United States
    Econometric Model of the United States is a large-scale macroeconometric model developed to analyze and forecast the U.S. economy, particularly associated with the pioneering work of economist Lawrence Klein.
  • E. Klein–Tinbergen macroeconometric models
