For an arbitrary subset I of and for a function f defined on I, the number of zeros of f on I will be denoted by In this paper we attempt to characterize all linear transformations T taking a linear subspace W of C I into functions defined on J (I J β ) such that Z I f = Z J Tf for all f β W .

The authors have presented in [1] a technique to generate transformations "Y of the set Pn of n th degree polynomials to itself such that if p E Pn has all its zeros in (c, d) then T{p} has all its zeros in (a, b), where (a, b) and (c, d) are given real intervals. The technique rests upon the deriva
The dynamic linear model (DLM) with additive Gaussian errors provides a useful statistical tool that is easily implemented because of the simplicity of updating a normal model that has a natural conjugate prior. If the model is not linear or if it does not have additive Gaussian errors, then numeric
