  A model of neutrino oscillation experiments is constructed. The experiments
incorporated are: solar neutrinos (Chlorine, Gallium, Super-K, and SNO),
reactor neutrinos (Bugey and CHOOZ), beam stop neutrinos (LSND decay at rest
and decay in flight), and atmospheric neutrinos. Utilizing this model and the
standard three-neutrino mixing extension of the standard model, the data are
analyzed. Solutions for the mixing angles and mass-squared differences are
found to occur in pairs corresponding to the interchange $\Delta m^2_{12}
\leftrightarrow \Delta m^2_{23}$. Two pairs of solutions are found that
reasonably reproduce the data, including the LSND data. These solutions are
$\theta_{12}\approx 0.5$, $\theta_{13}\approx 0.1$, $\theta_{23}\approx 0.7$,
$\Delta m^2_{12} \approx 5\times 10^{-5}$ eV$^2$ and $\Delta m^2_{23} \approx
0.2$ eV$^2$ or 2.4 eV$^2$. Other statistically significant solutions are also
found which produce negligible oscillations for the LSND experiments.
