Dear all, Imai-san, and Asakawa-san.
Thank you for your reply for the garbage e-mail. Both of your view are
interesting for me...

Thank you for your kind words.
> なかなか面白い調査ですね。調査時点はいつ頃です
1994. It is conducted every year. And the topics are changed nearly
every year.
We can use micro-data of this survey in many countries, including Japan.
Although Japanese statistical law strictly prohibits the disclosure of
micro-data, this data can be used in many countries, I think. It was
conducted by NHK and sample size are very very small, say 1500.
Despite such
a small sample size, I need to use it because there is no other
accessible Japanese
micro-data.
As IMAI-san pointed out, I did not consider missing data.
It would be different from those results if missing data are included.
