Retention and Graduation Rate Data and Models - Northeastern States
    In the fall of 2014 I began a survery of Friday classes of all schools in Massachusertts, the purpose being to see broadly how the four day week was growing, not just in flagship schools or the Ivy League or big cities.  As I finished Massachusetts, it occurred to me that I could get retention and graduation rates for most of these schools and I could also get acceptance rates to control for the quality of students.  With this control I could run a mutliple regression and measure the effect of the four day week on retention and graduation.  The results were very encouraging.  While Massachusetts was small so that it was hard to get statistical significance, the effect was substantial and I have been enlarging the sample ever since.  The quality of the model is already impressive and I have written a draft of a paper that I intend to publish and that hopefully will set higher education back on a five day path.
    Here is what I have so far in the order that I created it.  I have submitted a paper for publication with the hope that soon my findings will be widely known.  In the meantime, I have begun to work on Maryland.
                    Massachusetts
                    Rhode Island
                    Connecticut
                    Maine
                    New Hampshire
                    Vermont
                    New York
                    New Jersey
                    Pennsylvania
    Here are printouts of the basic regressions that I have in the paper.  Other specifications were tried, but none improved on the simple linear model.
And here is the spreadsheet that has all the data  and links to sources of some of the data.
