For a REGULAR YAGI do the parasitic element's induced voltages cause 
radiation which then cause currents in the neighboring elements and so on? 
I am pretty sure that this is true but do these SECONDARY currents have the 
amplitude and phase to have much effect on the total pattern?

Do antenna modelling programs take these secondary currents and radiation 
into account when summing up the segments and elements?
