nonnumerical character to specify infinity (∞).
 You can rotate the bivariate normal distribution in 3D by clicking and dragging on the graph.
 Probability Results
are reported in the bottom text area.
 This graphical bivariate Normal
probability calculator shows visually the correspondence between
the graphical area representation and the numeric (PDF/CDF) results.
However, the reported probabilities are approximate
(e.g., accuracy ~10^{2}) due to the finite
viewing window of the infinitely supported Normal distribution, the
limited numerical precision of the inputs (domain) and outputs (range),
numeric Cholesky decomposition calculation, and finite Monte Carlo simulation.
Users that require highprecision calculations are encouraged to
use the
SOCR highprecision numerical probability calculators.
The
BVN2 version
provides more accurate estimates of the Bivariate Normal Distribution
probability calculation and relies on the modern 3D Plotly visualization.
