We perform Monte Carlo simulations of pulsar periods, pulse-widths and
magnetic inclination angles. Using the available
observational data sets we study possible parent
distribution functions by means of the Kolmogorov-Smirnov
significance tests. We also use an additional condition that the
numbers of generated interpulses, whether from both magnetic poles
or from a single pole, are at the observed levels. We derived
a model distribution function of magnetic inclination angles
which has a local maximum near 
and another
weaker one near 
. The gamma function is a plausible
distribution function describing pulsar periods.
The average beaming fraction describing the fraction of observable
radio pulsars is about 0.12.
