DESCRIPTION:Alternative theories for structure formation often involve a f
 ifth force which could affect the clustering properties of matter. Such th
 eories are highly nonlinear because one must ensure that the fifth force i
 s weak enough in high density regions to pass the current laboratory tests
 \, while in low density regions it can be of gravitational strength. In th
 e standard LCDM model analytical formulae exist to predict the nonlinear s
 tructure formation in agreement with numerical simulations\, while this ap
 proach is difficult to apply to the alternative theories. Here we propose 
 an extension to this approach that solves this problem.
