To obtain values of this latter predictor, participants estimated the proportion of their close friends who were involved in each of the same nine activities on a five-point scale (ranging from 0 = none, to 4 = all).

A linear change trajectory may also be reasonable for many other sample members (including subjects 45, 314, 442, 514, 723, 949, 1105, and 1542) if we are correct in regarding the observed deviations from the fitted trajectory as random error. For five adolescents (subjects 9, 268, 918, 978, and 1552), observed and fitted values are more disparate.

With the nonparametric approach, you let the “data speak for themselves” by smoothing across temporal idiosyncrasies without imposing a specific functional form. With the parametric approach, you select a common functional form for the trajectories—a straight line, a quadratic or some other curve—and then fit a separate regression model to each person’s data, yielding a fitted trajectory.
