# Brazilian Network of PhDs Working with Probability and Statistics

## TL;DR

This paper maps the network of Brazilian PhDs in Probability and Statistics, revealing regional disparities, centrality of certain states, and indicating a developing, non-cohesive national research community.

## Contribution

It provides the first comprehensive analysis of the Brazilian Probability and Statistics PhD network, highlighting regional differences and network structure.

## Key findings

- Greater concentration of researchers around graduate program cities
- States with doctoral programs are most central in the network
- The network shows regional disparities and is in a maturing stage

## Abstract

Statistical and probabilistic reasoning enlightens our judgments about uncertainty and the chance or beliefs on the occurrence of random events in everyday life. Therefore, there are scientists working with Probability and Statistics in various fields of knowledge, what favors the formation of scientific network collaborations of researchers with different backgrounds. Here, we propose to describe the Brazilian PhDs who work with probability and statistics. In particular, we analyze national and states collaboration networks of such researchers by calculating different metrics. We show that there is a greater concentration of nodes in and around the cites which host Probability and Statistics graduate programs. Moreover, the states that host P & S Doctoral programs are the most central. We also observe a disparity in the size of the states networks. The clustering coefficient of the national network suggests that this network and regional differences especially with respect to states from South-east and North is not cohesive and, probably, it is in a maturing stage
