Groundhog Day Weather History for Peoria

Groundhog Day is celebrated on February 2. According to folklore, if is cloudy when a groundhog emerges from its burrow on this day, then spring will come early. If it is sunny, the groundhog will see its shadow and retreat back into its burrow, and winter weather will continue

A Practical Guide to Regression Discontinuity

Regression discontinuity (RD) analysis is a rigorous nonexperimental1 approach that can be used to estimate program impacts in situations in which candidates are selected for treatment based on whether their value for a numeric rating exceeds a designated threshold or cut-point.

discontinuity in the shear force at B allows the discontinuity in slope of M -P b at that point. Our linear, ordinary, second Mb(x) order differential equation for the deflection of the neutral axis becomes, for x < L/4 x 2 -P(L-a) x > a dv Mb() x 3P x < a dx 2

Reviews, Reputation, and Revenue: The Case of Yelp

The regression discontinuity design around rounding rules offered in this paper will also allow for identification of the causal impact of reviews in a wide variety of settings, helping to solve a classic endogeneity problem. For example, Amazon.com has consumer reviews that are aggregated and presented as a rounded average.
