Scenario: From time to time a historian discovers an unsigned manuscript, musical composition, or work of art. Scholars in these fields have various methods to infer the creator of such an unattributed work, and sometimes turn to statistical methods for assistance. Let’s consider a hypothetical example based on the Sonatas data.

a. Run a logistic regression using Parta and Partb as independent variables and Composer as the dependent variable. Report the results.

b. (Challenge) Suppose that we find a composition never before discovered.
Parta is 72 measures long and Partb is 112 measures long. According to our model, which composer is more likely to have written it? Why?
