  This work presents a novel method to estimate the effective opening angle of
CBe star disks from projected axis ratio measurements, obtained by
interferometry using Bayesian statistics. A Monte Carlo scheme was used to
generate a large set of theoretical axis ratios from disk models using
different distributions of disk densities and opening angles. These theoretical
samples were then compared to observational samples, using a two-sample
Kolmogorov-Smirnov test, to determine which theoretical distribution best
reproduces the observations. The results suggest that the observed ratio
distributions in the K-, H-, and N-band can best be explained by the presence
of thin disks, with opening half-angles of the order of 0.15$^{\circ}$ to
4.0$^{\circ}$. Results for measurements over the H$\alpha$ line point toward
slightly thicker disks, 3.7$^{\circ}$ to 14$^{\circ}$, which is consistent with
a flaring disk predicted by the viscous disk model.
