Agenda Midterm Review: Power Multiple Regression Project Proposal Guideline

Power Probability that a fixed level alpha significance test will reject H 0 when a particular alternative value of the parameter is true. 1. State H 0, H a, the particular alternative we want to detect, and significance level alpha 2. Find rejection region of sample statistic (ex, proportion) 3. Calculate P( observing these value of sample statistic when alternative is true)

Increasing power Increase alpha Consider a particular alternative that is farther away from null hypothesis Increase sample size Decrease sigma

Option A: Review of others’ paper Option B: Analysis of data Poster Presentation during reading period Blank Review Form TFs will grade the posters without access to any of the student’s reviews. The instructor will grade the reviews before seeing any of the TFs’ poster reviews and grades.

Project Proposal: Option A Locating a scientific paper Research journals Visit library hollis.harvard.edu Poster the afore-mentioned results of statistical tests t-test, chi-square, multiple regression Graphical display Strength and Weakness of statistical analysis

Project Proposal: Option B Search data Some links are on the class website MIT-Harvard Database Finance.google.com, Background, Study of design or Observational study, Methods, Results, Conclusions

What I am looking for Your effort to gather data Right use of statistical analysis How much you give your time and thinking to your project? Clear display of your result
