Data in statistical practice often consist of nonnegative measurements that exhibit positive skewness. The inverse Gaussian (IG) family of distributions provides a versatile and flexible model for ...

Let (Y, (X i ) 1≤i≤p ) be a real zero mean Gaussian vector and V be a subset of {1,...,p}. Suppose we are given n i.i.d. replications of this vector. We propose a new test for testing that Y is ...
