In analysing a clinical trial with the logrank test, the hazards between the two groups are usually assumed to be proportional. Nevertheless, this hypothesis is no longer valid with unobserved covariates. As a consequence, there is a loss of power of the logrank test for testing the null hypothesis

In this article, we study the Cauchy problem of generalized Boussinesq equations. We prove the local existence in time in Sobolev and weighted Sobolev space through Fourier transforms. Then our main result is to prove that the supremum Ε½ . norm of the solution n, Β¨with sufficiently small and regular
## Abstract This paper discusses two alternative innovation representations (forward and backward) of a state space model of a multivariate weakly stationary time series, and suggests estimators of system matrices and innovation noise covariances which are alternative to these based on stochastic r
