  We study the distributions functions for global partial density of states
(GPDOS) in quasi-one-dimensional (Q1D) disordered wires as a function of
disorder parameter from metal to insulator. We consider two different models
for disordered Q1D wire: a set of two dimensional $\delta$ potentials with an
arbitrary signs and strengths placed randomly, and a tight-binding Hamiltonian
with several modes and on-site disorder. The Green functions (GF) for two
models were calculated analytically and it was shown that the poles of GF can
be presented as determinant of the rank $N\times N$, where $N$ is the number of
scatters. We show that the variances of partial GPDOS in the metal to insulator
crossover regime are crossing. The critical value of disorder $w_c$ where we
have crossover can be used for calculation a localization length in Q1D
systems.
