LEC #  TOPICS 

Part 1: Introduction: Research Methods and Challenges  
1  Introduction 
Part 2: Mathematical Tools This section of the course reviews basic mathematical tools. You will also perform simple regression analyses using STATA® and we will use the functions that you estimate in the mathematics review. 

2  Functions and Limits 
3  Derivatives 
4  Maximization 
5  Sums and Integrals 
Part 3: Probability and Models of Data This section of the course develops the mathematical concepts used in statistics. Three ideas are essential: Random Variable, Density Functions, and Expectations. 

6  Random Variables, Populations and Samples 
7  Probability: Two Laws of Probability, Bayes Theorem 
8  Probability Functions: Binomial, Bernoulli, Poisson Uniform, Normal 
9  Expected Value: Mean, Variance, Covariance 
10  Sums of Random Variables and Limit Theorems, Law of Large Numbers, Central Limit Theorem 
Part 4: Statistical Methods In this section of the course, we develop the three ideas of statistics using probability theory. These ideas are (1) data can be summarized with a probability function, (2) we can optimize that function to estimate unknown parameters of the population, and (3) our estimates are uncertain measures of the population parameters, but we can summarize that uncertainty succinctly. 

11  Data Model: Summary and Assumptions 
12  Estimation: MLE and MOM 
13  Inference: Confidence Interval and MSE 
Part 5: Statistical Models: Conditional Distributions and Causality In this section, we apply the mathematical and statistical ideas develop to specific problems. The main idea in this section is that social scientific reasoning involves conditional statements of the form if X then Y. We focus on the tools for studying such relationships. 

14  Differences of Means 
15  Analysis of Frequencies and Variance 
16  Regression 
17  Regression (cont.)
