The use of 2-point statistics (correlation functions and Power spectra) has 
been the common tool to analyse the galaxy distribution and obtain constraints 
on cosmological and galaxy formation models. But it does not contain all the 
information available from the galaxy field, and theoretical understanding 
combined with improved computation techniques allow us to include other 
statistics and observables to obtain additional constraints. 
In this talk I present results from the analysis of the WiggleZ 3-point 
correlation function, which measures the probability of finding triangles in 
the galaxy field; using this statistic we can constrain galaxy bias and 
estimate the cosmological growth function at different epochs. Secondly, 
I present preliminary results of constraints in the growth rate of structure 
combining clustering from the WiggleZ and BOSS surveys sharing the same 
volume, using the method of modelling redshift-space distortions. With the 
current surveys, applying these methods we estimate the evolution of cosmic 
growth, finding agreement with the predictions of the concordance LCDM 
universe. I will discuss the outlook for future surveys, where these methods 
promise to improve the power of prediction from galaxy surveys, in order to 
understand questions on the nature of dark energy and gravity models.
