ABSTRACT
Constraints on cosmological parameters depend on the set of parameters chosen to define the model which is compared with observational data. I use the Akaike and Bayesian information criteria to carry out cosmological model selection, in order to
determine the parameter set providing the preferred fit to the data. Applying the information criteria to the current cosmological data sets indicates, for example, that spatially-flat models are statistically preferred to closed models, and that possible
running of the spectral index has lower significance than inferred from its confidence

this paper is about the maths and options chosen to represent
a model, can someone give me an opinion about the mathmatical
