Description: Provides vocabulary growth dataset from Huttenlocher et
        al. (1991) <https://doi.org/10.1037/0012-1649.27.2.236>. This
        dataset is useful educationally because it features
        longitudinal/repeated measures growth data. It is also unusual
        because the only fixed effect predictor is quadratic time--that
        is, there is no intercept or linear time terms.
