huttenlocher1991: Vocabulary growth in 22 infants (Huttenlocher et al., 1991)

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.
