  • Software: R, S-Plus, Matlab, SPSS, Econometric Views, Statgraphics.

Joan Crespo

María Rosario López

  • Obtaining quantitative indicators to assess the impact of gender on health. Can be applied to other areas such as research or institutions, etc.
  • Designing of surveys and sampling designs.
  • Using different multivariate analysis techniques:
    • Factor analysis to obtain indicators (scores) through extensive surveys rather than intensive surveys in order to improve the quality of information.
    • Correspondence analysis to determine profiles or groups through quantitative information and categorical variables.
    • Multivariate regression models (linear, logistic and Cox regression) to model the relationship between variables in different contexts (quantitative, categorical or time dependent).
  • Using different statistical software (mainly SPSS and SAS).

Rosario Romera

  • Composite indicators.
  • Multivariatetechniques.
  • Robustness.
  • Stochastic optimization.
  • Markovdecision processes.

Areas of research

  • Mathematical models which explain the process of citation: Axioms / alternatives to the so-called “Matthew effect”.
  • Create a dynamic model of social networks that satisfactorily explain the distribution of citations.
  • To study citation speed in different areas.
  • To study the distribution of citations.
  • To design contrasts for such distributions, e.g., lognormal, exponential, etc.
  • To identify priority fields on science (cluster analysis of data).
  • Development of university rankings, in particular “Statistical methods for building Composite indicators” as a strategic tool for universities.
  • When and how mathematics, physics and / or economic theory enters into the applied area? A “survival” model designed to measure how long an article on theory takes to be cited by an academic article in the applied area. A comparative study of academic journals is proposed as well as an analysis of their progress over a given period of time.
  • Development of descriptive measures to compare the scientific production of different institutions.
