cumulative Z-structure
Can you say a little more about how the cumulative Z-structure is defined? I can see that it's defined on p. 390 of Raudenbush's HLM 6 book, but I can't get to that page on Google Books to see how it's actually specified ... On Sun, Jul 22, 2018 at 10:51 AM Peter Paprzycki

In longitudinal, repeated-measure intervention research, the authors of HLM 6.03 software recommend using a so called cumulative Z-structure to reflect the carry-overs of intervention effects from one measurement occasion to another. Is there an equivalent of this structure with the use of the lme function? The data set up is annual observations nested in students crossed by teachers and schools with intervention on and off between years. I appreciate guidance. Thank you.
