<h2>
Purpose
</h2>
Evaluate error function for generalized linear model.
<p><h2>
Synopsis
</h2>
<PRE>
e = glmerr(net, x, t)
[e, edata, eprior] = glmerr(net, x, t)
[e, edata, eprior, y, a] = glmerr(net, x, t)
</PRE>
<p><h2>
Description
</h2>
<CODE>e = glmerr(net, x, t)</CODE> takes a generalized
linear model data structure <CODE>net</CODE> together with a matrix <CODE>x</CODE>
of input vectors and a matrix <CODE>t</CODE> of target vectors, and evaluates
the error function <CODE>e</CODE>. The choice of error function corresponds
to the output unit activation function. Each row of <CODE>x</CODE>
corresponds to one input vector and each row of <CODE>t</CODE> corresponds to
one target vector.
<p><CODE>[e, edata, eprior, y, a] = glmerr(net, x, t)</CODE> also returns
the data and prior components of the total error.
<p><CODE>[e, edata, eprior, y, a] = glmerr(net, x)</CODE> also returns a matrix <CODE>y</CODE>
giving the outputs of the models and a matrix <CODE>a</CODE>
giving the summed inputs to each output unit, where each row
corresponds to one pattern.
