SGP-class

is.SGP

The formal S4 class for SGP. This class stores the data object for use with the functions <code><a href="/link/analyzeSGP?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::analyzeSGP">analyzeSGP</a></code>, <code><a href="/link/combineSGP?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::combineSGP">combineSGP</a></code>, <code><a href="/link/summarizeSGP?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::summarizeSGP">summarizeSGP</a></code>,
and <code><a href="/link/visualizeSGP?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::visualizeSGP">visualizeSGP</a></code>. The SGP class contains and organizes all the results associated with SGP analyses. <code><a href="/link/is.SGP?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::is.SGP">is.SGP</a></code> tests for membership for this class.

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.

SGP-class function

Objects can be created by calls of the form <code>new("SGP", ...)</code>, but this is not encouraged. To instantiate a new instance of SGP class use the function <code><a href="/link/prepareSGP?package=SGP&version=0.7-1.0" rd-options="" data-mini-rdoc="SGP::prepareSGP">prepareSGP</a></code> instead.<p></p><p><code>is.SGP(x)</code></p>
