Abstract


The objective pursued in this article is to study Correspondence Factor Analysis (CA), which is an extremely powerful tool for synthesizing information, widely used when dealing with a large mass of qualitative data. treat. It also makes it possible to identify existing relationships between individuals by evaluating their similarities, as well as relationships between variables by evaluating their connections, and obtain a simple representation of the data cloud in a low-dimensional space closer to reality. Factorial analysis of the data was applied using R software, version 4.3.1 (2023-06-16 ucrt). The application of the said method was carried out on «the nutritional status of Congolese children under 5 years old, from January to December 2022, PRONANUT, DR Congo».
