<p class="MsoNormal">Dear Fieldtrippers,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve been hitting a pretty high memory ceiling, so I’m trying to reduce the use of RAM as much as possible.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am at the point of using (source)statistics, in which I need to (t-)test against zero. Normally, I would just create dummy FT data-structures, in which I replace the parameter that is tested with 0. However, in my case this would result
 in an asphyxiating (more than) doubling of data in memory. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anyone already created a ft_statfun that simply tests against a scalar (for all data points)? Or, if I would need to write my own, which existing ft_statfun would be most convenient do you think? Or perhaps there is another way around
 it?<o:p></o:p></p>
