We have computed a series of realistic and self-consistent models able to reproduce the observable characteristics of HII galaxies in a star bursting scenario, using the technique developed by Martín-Manjón et al. (2008). Each model is characterized by three parameters that determine the evolution of the modeled galaxy: the initial efficiency of star formation, the strength of the bursts, and the time elapsed between them. Our model technique gives results that reproduce the observed abundances, diagnostic diagrams and equivalent width vs. colour relations for local HII galaxies in every evolutionary stage, and can be extrapolated to other objects under different assumed star formation scenarios. Some preliminary results about the application of the models using statistical methods, are shown.
