My name is Kaz and  I am a data analyst/methodologist in Washington DC area (USA).  I use this website for myself. Some materials may be useful for you.  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 originally from a small town Akitsu-cho (Hiroshima, Japan).  Here is a family reunion photo from 80s.  I have about 25 cousins.  In this picture, I'm holding my dog.

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