<H2>Class Description</H2>
This object produces a stochastic sequence of dividends. The process
is independent of the market and agents, depending only the parameters
that are set for the dividend process (and on the random number generator).

<H2>Instance Methods</H2>
<A NAME="- dividend"></A><H3><A NAME="//apple_ref/occ/instm/Dividend/dividend">dividend</A></H3><P>
<CODE>- (double)<B>dividend</B>
</CODE><P>
Returns the next value of the dividend. This is the core method
of the Dividend object, for which all else exists. It does NOT use
the global time, but simply assumes that one period passes between
each call. Note that "time" may not be the same as the global
variable "t" because shifts are introduced to maintain phase when
certain parameters are changed.

<A NAME="- initNormal"></A><H3><A NAME="//apple_ref/occ/instm/Dividend/initNormal">initNormal</A></H3><P>
<CODE>- <B>initNormal</B>
</CODE><P>
Creates a Swarm Normal Distribution object
<P><HR WIDTH=25% ALIGN=LEFT>
<A NAME="- setAmplitude:"></A><H3><A NAME="//apple_ref/occ/instm/Dividend/setAmplitude:">setAmplitude:</A></H3><P>
<CODE>- (double)<B>setAmplitude:</B>(double)<EM>theAmplitude</EM>
</CODE><P>
Sets the "amplitude" parameter. Returns the
value actually set, which may be clipped or rounded compared to the
supplied argument. See "-setDivType:".
