Online Econometrics Resources / Team LEF

Breusch-Pagan LM statistic test The Breusch-Pagan LM statistic tests the random effects model against thepooled OLS model. The specific hypothesis under investigation is the following:H0: σ2α = 0H1: σ2α ≠ 0The random effects model reduces to a pooled OLS regression under the null (when σ2α = 0).The test is based on OLS residuals built from […]

What is variance? How it differs from co-variance? How these are related to correlation? The variance means the quality of being different divergent from the norm. It measures how far each number in the set is from the mean (average), and thus from every other number in the set. Variance is often depicted by this symbol: σ2.

What is Real Business Cycle model? How is it different from the Keynesian model? Role in DSGE model?

Online Econometrics Resources / Team LEF

Real business cycle model is based on business cycles and incorporates technological shock as the prime reason for fluctuation in economic activity. Money is neutral with no impact on real variables. These models hold the view that fluctuations in aggregate economic activity are an antidote to the uncertainty in agents’ environment arising from exogenous technology

Basic features of DGSE model

Online Econometrics Resources / Team LEF

Dynamic General Stochastic Equilibrium (DGSE) models are well grounded theoretically, in harmony with the empirical evidence to predict and provide accurate interpretation of past and present economic events. The term Dynamic implies the model is time-dependent. It involves expectations regarding future outcomes tightly knit with the present decision of the economic agents. Economic agents’ objective

Everything You Ever Wanted to Know About Building Your Econometrics Model

Online Econometrics Resources / Team LEF

There is little doubt that every economic theory we studied is based on theoretical modeling first. It sprouted from an idea which later on was served to the world with improvements; assumptions, hypothesis tests and results came into prominence. These models are all the simplified versions of reality. Starting from the most basic law of
