⚠️There's a newer version (2.2-0.0) of this package.Take me there.

SGP (version 1.1-0.0)

An R Package for the Calculation and Visualization of Student Growth Percentiles & Percentile Growth Trajectories.

Description

Functions to calculate student growth percentiles and percentile growth projections/trajectories for students using large scale, longitudinal assessment data. Functions use quantile regression to estimate the conditional density associated with each student's achievement history. Percentile growth projections/trajectories are calculated using the coefficient matrices derived from the quantile regression analyses and specify what percentile growth is required for students to reach future achievement targets.
