Abstract : We present a statistical study of different properties of four classes of isolated neutron stars, namely Isolated Radio Pulsars (IRaPs), which emit regular radio pulse that are detectable in periodicity searches, Rotating Radio Transients (RRATs), which emit sporadic radio pulses that are detectable in single pulse searches, X-ray Dim Isolated Neutron stars (XDINs), which are seen only in thermal X-rays and Magnetars, which are seen in more luminous quiescence X-rays accompanied by strong outbursts. The parameters explored are measurable parameters like the spin period and the rate of change of the spin period, as well as derived parameters like the characteristic age, the spin-down power, the surface dipolar magnetic field, and the dipolar magnetic field at the light-cylinder. We employ both one-dimensional and two-dimensional Kolmogorov-Smirnov tests. We report that distributions of various parameters of these classes are statistically distinct.
