Source: CouchSurfing US dataset. Legend: *, ** , ***. N = 67,183.
Each variable is time-demeaned to take into account any secular trends. We controlled for heteroskedasticity by dividing each variable by its time dependent standard deviation. We addressed autocorrelation of individual observations by subtracting the forward mean, which corresponds to the mean of all future observations for each individual (Helmert transformation). The reported coefficients are -scores.
