My name is Kaz and  I am a data analyst/methodologist in Washington DC area (USA).

I use this website for myself.

Topics include SAS & R programming, hierarchical linear modeling (HLM), Rasch model analysis, RCT (randomized control trial), QED (quasi-experimental design), PSM (propensity score matching), etc. I'm a certified What Works Clearinghouse reviewer (Group design 4.0). With my colleagues, I've designed and conducted many QEDs and RCTs.

I'm working on my R memo lately.


I'm also slowly translating Takuboku Ishikawa's tanka's.



I'm originally from a small town Akitsu-cho (Hiroshima, Japan).   I have about twenty five cousins.  In this family reunion picture from 80s, I'm holding my dog. I believe this was taken in 1985 or 86, when I was prepping for college entrance exams.

I also found that my grandpa's cousin moved to Peru in 1900 and I have a massive number of Peruvian cousins (and a majority of them immigrated to Japan in 80s and 90s). I look forward to seeing them in Japan in the near future.

My hometown Akitsu-cho has a beautiful Sakura mountain park.

I can be reached by email  (k u e k a w a AT GMAIL COM).
