We can study only using notes, pens, and computers. Thus, we can study not only in offices, but also in our houses and trains. Thus, our research styles are free, less restrictive, and comfortable..

We can easily collaborate with foreign researchers simply by emailing about ideas. Indeed, we have performed such collaborations.
Further, we published papers in international journals. They include Psychometrika, Computational Statistics and Data Analysis, Computational Statistics, Advances in Data Analysis and Classification.
