Medical statistics and Data Science

Data are crucial for decision making
But data do not speak for themselves!!

Welcome to MS&DS (Medical Statistics and Data Science)

MS&DS is interested in mathematics and mathematical statistics, especially interested in mathematics behind statistical and epidemiological methodologies applied in medical researches.

We have experience in a wide range of medical research such as study design, data collection, data management, statistical analysis, and data interpretation.

Furthermore, we know how to explore dataset beyond the medical field and make a report based on the dataset.

The site is young but it keeps growing!
