An efficient method for construction of an analytic S matrix from experimental data based on the use of the statistical Pad\'e approximation is proposed. The method is applied to the energy-dependent phase-shift analysis of the elastic scattering of deuterons by alpha particles in the energy range 0.87${\mathit{E}}_{\mathit{d}}$5.24 MeV, and partial-wave phase shifts for l=0,1,2 are obtained. In addition, the energies and widths of the three known $^{6}\mathrm{Li}$ resonances are obtained, together with the energy of the $^{6}\mathrm{Li}$ bound state and the vertex constant of the virtual decay $^{6}\ensuremath{\rightarrow}^{2}$H${+}^{4}$He.
