To perform statistic analysis we'll use PLINK/SEQ, which acdcepts VCF files. It is similar in lexic to PLINK, traditionally used for GWAS data.
As today (March, 2015) there are some features of PLINK/SEQ which do not perform perfect, such as its R library, because they say they are developing a beta version to be released “soon”. However, there is a basic tutorial, and a extended tutorial which are sufficient to allow you to play around with your data, get basic statistics and analysis.
