Description: Functions to calculate growth percentile and projections for students using large scale, longitudinal assessment data. 
	These norm referenced growth values are presently used in some state testing and accountability systems. The functions use 
	quantile regression techniques package to estimate the conditional density associated with each students achievement history. 
	Student Growth Projections (i.e., percentile growth trajectories) are calculated using the coefficient matrices derived from 
	the quantile regression analyses and help to identify what it will take for students to reach future achievement targets.
