<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).

		<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 &quot;time&quot; may not be the same as the global 
variable &quot;t&quot; because shifts are introduced to maintain phase when 
certain parameters are changed.
	
		<P><HR WIDTH=25% ALIGN=LEFT>
		<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 &quot;amplitude&quot; parameter. Returns the 
value actually set, which may be clipped or rounded compared to the 
supplied argument. See &quot;-setDivType:&quot;.
	
		<P><HR WIDTH=25% ALIGN=LEFT>
		<A NAME="- setBaseline:"></A><H3><A NAME="//apple_ref/occ/instm/Dividend/setBaseline:">setBaseline:</A></H3><P>

		<CODE>- (int)<B>setPeriod:</B>(int)<EM>thePeriod</EM>
			
		</CODE><P>
		Sets the &quot;period&quot; parameter. Returns the 
value actually set, which may be clipped compared to the supplied 
argument. See &quot;-setDivType:&quot;.
	
		<P><HR WIDTH=25% ALIGN=LEFT>
		<A NAME="- setmaxdividend:"></A><H3><A NAME="//apple_ref/occ/instm/Dividend/setmaxdividend:">setmaxdividend:</A></H3><P>
