splineMatrix-class

date-class

The formal S4 class for coefficient matrices produced from the <code><a href="/link/studentGrowthPercentiles?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::studentGrowthPercentiles">studentGrowthPercentiles</a></code> function. This class stores the knots and boundary knots used the coefficient matrix object for the production of student growth percentiles and projections.

classes

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.

splineMatrix-class function

Objects can be created by calls of the form <code>new("splineMatrix", ...)</code>, but this is not encouraged.  Previously produced coefficient matrices MUST be bound to the IDENTICAL knots and boundaries used to create them. Use the function <code><a href="/link/studentGrowthPercentiles?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::studentGrowthPercentiles">studentGrowthPercentiles</a></code> instead.
