Note. Models were estimated for all possible knots (last 24 hours, last 2 days, last 3 days, last week, last 2 weeks, last month, last 3 months, last 6 months). Linear coefficients and standard errors for corresponding segments and Bayesian Information Criterion (BIC) are displayed. Segment 1 includes time frames before the knot. Segment 2 includes the knot and time frames after the knot including the last year time frame.

The difference between pairs of coefficients printed in bold is significant at p < .05.

* p < .05.

** p < .01.

*** p < .001.
