  We study the possibility to reproduce the statistical relations of the
sunspot activity cycle, like the so-called Waldmeier relations, the cycle
period - amplitude and the cycle rise rate - amplitude relations, by means of
the mean field dynamo models with the fluctuating \alpha-effect. The dynamo
model includes the long-term fluctuations of the \alpha-effect and two types of
the nonlinear feedback of the mean-field on the \alpha-effect including the
algebraic quenching and the dynamic quenching due to the magnetic helicity
generation. We found that the models are able to reproduce qualitatively and
quantitatively the inclination and dispersion across the Waldmeier relations
with the 20% fluctuations of the \alpha-effect. The models with the dynamic
quenching are in a better agreement with observations than the models with the
algebraic \alpha-quenching. We compare the statistical distributions of the
modeled parameters, like the amplitude, period, the rise and decay rates of the
sunspot cycles, with observations.
