Jessica Kitch A+ Ashish: - in general well-done and well reported - maybe say something about the EDA in the body of the report - tech appendix is nicely done BJ: - Excellent, rich exec summary, takes advantage of log-OR's found - correct cond indep found from loglinear, but not really interpreted - nice tough pursuit of logistic regression, exploiting loglinear findings Jennifer Fridd A Ashish: - Should probably try to use fewer equations/formulae while reporting the analysis, and avoid relying on the equations in the descriptive text - most findings of the log-linear analysis were not reported in the exec summary BJ: - summary nice - when you say "did not signif influence response" in a loglinear model what you mean is that the counts were not very different at different levels - interesting explicit exploration of models conditional on urban, after discovering that (race,grade)indep(goals,gender)given(urban) Alan Charness: B+ Ashish: - maybe should also report log odds from logistic regression in the exec summary and conclusion - no EDA - need more detailed analysis section - could describe the graphical representation better BJ: - good job but not well backed up by technical appx's. Eg., where's * eda * model selection * etc. Alexis Lubensky B+ Ashish: - No abstract/exec summary - Analysis description is sketchy - at end, qualitatively suggests some conclusions that could have been obtained by logistic regression BJ: - very good as far as it goes, but missing * exec summary * logistic regression or data summaries to back up concl's at end - summary of analyses a bit too technical, esp incl qq plot Ty Douglas B+ Ashish: - Part of exec summary reads like analysis - analysis description sounds a bit generic - could make it more specific by naming variables involved, etc. - don't know where he went wrong but should have had more 2-factor interactions with "urban" in the loglinear model - started on logistic models but gave up for unknown reasons BJ: - good start but got off on wrong foot by treating sampling zeros in race x urban as structural zeros. distorted model Jian Bo Yu B+ Ashish: - doesn't mention possibility of logistic regression analyses - could try using step BJ: - Nice loglinear analysis and EDA - didn't fully interpret graphical model at the end - no logistic regression analyses Kary Myers B+ Ashish: - Exec summary summarizes the procedure used and not the findings - Doesn't do any of the loglinear stuff but does a good complete job of addressing the problem she states. - emphasizes prediction. does sample-splitting: train/test. possible influence of the reference cited BJ: - very nice logistic analysis, but misses the loglinear analysis that might have guided some of this Christine Hou B+ Ashish: - Discusses what she'd expect to find in the data in the exec summary and doesn't clearly distinguish her actual findings from what she expects to find - doesn't mention residual analysis - qualititative suggestions of what could be addressed with logistic regression BJ: - Nice job of log-linear analysis - draw the graph and interpret conditional independencies - logistic regression follow-ups? - model fit? Katy O'Leary C- Ashish: - Exec summary is short and not informative - Problem description is vague - seems to have misunderstood what was required in analysis section. Could have cut-and-pasted parts of her tech appx into the analysis section - omitted analysis item 10 in tech appx - spends disproportionate time on histo's and bar charts - seems lost in doing the GLM's. throws in everything indiscriminantly. doesn't look for interactions BJ: - good exploratory work with hist's / bar charts - none of the response variables are appropriate for the analyses performed---neither loglinear nor logistic. This is *serious* - no assessment of residuals, though they are plotted - summaries difficult to understand. What is a "criterion variable"? Use plain english. Craig Weiner B+ Ashish: - 1/2 sentence sketchy description of findings in the exec summary - the tech appx is more like what the analysis section ought to have been BJ: - good job with loglinear models - didn't do graph of final model or interp cond indep relations - no logistic regression followups Phoebe Papageorgiou B+ Ashish: - Didn't do any EDA but well done analysis BJ: - Nice job on loglinear analysis - didn't do graph of final model or interp of cond indep relations - no logistic regression analysis Manoo Halati B+ Ashish: - nice report of analysis, esp organization and tech appx BJ: - nice job of loglinear analysis - got some cond indep relats but didn't do graph of final model - no logisitic regression followups Yoo Jin Chang B- Ashish: (didn't see) BJ: - nice beginning of loglinear analysis (not completed) - good eda, resid plotting - no writeup - no logistic followup Huadong Wu A Ashish: (didn't see) BJ: - very nice job - loglinear great - good EDA, resid analysis - good logistic followup - would be nice to see more interp of logistic part in writeup
