Topics

• Different kinds of research
  • New models, estimation procedures, tests, simulations
• Types of data
  • Where would such types of data occur?
  • cross section (panel); time series
  • proxy variables
• Sampling link 1
  • Reasons: cost; statistical efficiency
• Minimum sample size
• Using Excel
  • data manipulation
  • estimation and testing
• Basic hypothesis testing (parametric)
  • logic
  • uses (averages/proportions; one/two samples; pair samples; two/one tail)
• Nonparametric
  • Chi-square: goodness of fit; contingency table
  • ....
• Regression and correlation
  • assumptions link 1 link 2
  • error term
  • omitted variables
  • dummy variables (interaction) (diff. b/t two means, and then more categories)
  • interpreting estimated slopes
  • multicollinearity
  • nonlinearities (log; rank)
  • logit and probit
