Statistical status quo
1. The understanding of systematicness and system complexity has added new ideas for the future development of statistics. With the rise of the trend of scientific integration, the research tentacles of statistics have extended to new fields, and the research on statistical methods of exploratory data has begun.
Secondly, the comprehensive integration method combining qualitative and quantitative methods will provide new ideas for the development of statistical analysis methods. The comprehensive integration method combining qualitative and quantitative methods was put forward by Professor Qian Xuesen in 1990.
Third, the infiltration of statistical science and other sciences will open up new fields for the application of statistics. The emergence of new frontier disciplines such as fuzzy theory and catastrophe theory provides new scientific methods and ideas for the further development of statistics.
