  Various spin observables (analyzing powers and spin-correlation parameters)
in $pd$ elastic scattering at $T_p = 800-1000$ MeV are analyzed within the
framework of the refined Glauber model. The theoretical model uses as input
spin-dependent $NN$ amplitudes obtained from the most recent partial-wave
analysis and also takes into account the deuteron $D$ wave and charge-exchange
effects. Predictions of the refined Glauber model are compared with the
existing experimental data. Reasonable agreement between the theoretical
calculations and experimental data at low momentum transfers $|t| \lesssim 0.2$
(GeV/$c)^2$ is found for all observables considered. Moderate discrepancies
found in this region are shown to be likely due to uncertainties in the input
$NN$ amplitudes. Qualitative agreement at higher momentum transfers is also
found for most observables except the tensor ones with mixed $x$ and $z$
polarization components. Possible reasons for observed deviations of the model
calculations from the data at $|t| > 0.2$ (GeV/$c)^2$ are discussed.
