Diversity and Application of Biplot Methods in Ecuadorian Research: A Systematic Literature Review

Abstract This systematic review examines the growing use of Biplot methods in Ecuadorian research, highlighting their relevance for simplifying complex data in fields such as agronomy and epidemiology. Through the analysis of 46 documents, a notable increase in the application of these techniques since 2020 is observed, reflecting the strengthening of local research capacity and the need for multivariate tools to interpret complex data. This review is unique in situating the use of Biplot methods within Ecuador’s scientific context, identifying patterns of international collaboration, particularly with institutions from Spain, and emphasizing the impact of these methods on data visualization for high-value scientific projects. The limitations include a focus on specific databases (Scopus, WoS, and SciELO), which could bias the results toward indexed publications. For the future, it is recommended to promote the use of Biplot methods in emerging areas of Ecuadorian research and establish more international partnerships to strengthen the impact of these techniques on local scientific development.
