Program Consists of instructions executing one at a time. Input A program gets data, perhaps from a file, keyboard, touchscreen, network, etc. Brainpower 0:02 / 0:15 Process A programs performs computations on that data, such as adding two values like x + y. Output A programs puts that data somewhere, such as to a file, screen, network, etc. Computational thinking Creating a sequence of instructions to solve a problem. Algorithm A sequence of instruct...

This document is a summary of everything you need to know for the endterm (and midterm) of the course 'Econometrics' (6012B0453Y) at the University of Amsterdam, taught by Hans van Ophem. This document includes the following topics: log and ln, expected value, variance, covariance, estimators, simple regression, least squares, gauss-markov, homoskedasticity, TSS, SSR, ESS, R^2, hypothesis testing,multiple regression, adjusted R^2, omitted variable bias, functional form, multicollinearity, SER,...

When there are omitted variables in the regression, which are the determinants of the dependent variable, then: correct answers the OLS estimator is biased if the omitted variable is correlated with the included variable If you have a regression model with two x's (independent variables), then omitting one variable which is relevant: correct answers can result in a negative value for the coefficient of the included variable, even though the coefficient will have a significant positive effect...

What is the systematic study of human behavior? correct answers organizational behavior What is the difference between correlation and causation? Give examples. correct answers A correlation is a statistical indicator of the relationship between variables. Causation means that changes in one variable brings about changes in the other; there is a cause-and-effect relationship between variables. What is a spurious relationship, and relatedly, omitted variable bias? correct answers In statist...

name the four types of specification errors correct answers choice of independent variables, functional form, misspecification of error term, measurement error what assumptions are satisfied when a model is overspecified? correct answers MLR1-4 what is the consequence of overspecification? correct answers the included variable may be correlated with other explanatory variable. No cost in terms of bias but increases sampling variance what assumption does Omitted variable bias violate? co...

MGSC 391 midterm Question and answers correctly solved 2024/2025 Common regression mistakes - correct answer linear regression for non linear relationship correlation does not equal causation reverse causality omitted variable bias data mining extrapolating omitted variable bias - correct answer leaving out important variables data mining - correct answer including too many variables Michael jordan - correct answer defense wins championships value of blocked shot - ...

What is econometrics? correct answers Tools of economic theory, math, and statistical inference are applied to the analysis of economic phenomena. How do we do econometrics? What are the steps involved? correct answers 1. Make a hypothesis 2. Collect data 3. Specify the model 4. Estimate the parameters 5. Check model specification - is the model good? 6. Test the hypothesis 7. Use the model to predict or forecast or answer questions Simple linear model correct answers yi= B1 + B2Xi +...
