A RDBESDataObject converted from package SDAResources dataset algebra

Source: R/data.R

This data set is derived from a fictional data for an SRS of 12 algebra classes in a city, from a population of 187 classes. The design is 1-stage cluster sampling with clusters of unequal sizes. Clusters are classes (class). Clusters (psu) are unequal sized (Mi). In each cluster, all students are selected (ssus, nrows). The total number of psus is known (187). The target variable is score.
