Introduction In the engineering practice, the values of observation are small samples.
This thesis integrate the theory of nonparametric statistics and that of transference for the application of flood frequency estimation, not only to improve the precision of small samples in the engineering calculation, but also to solve the difficulty of non-parameter statistics in choosing bandwidth, moreover, it lays a theoretical foundation for the application of non-parameter statistics in many other fields.
