The program Bivar1c.exe
is freeware and can be downloaded by following the link. The programme is
written in Delphi 4Ò
and requires Windows 95Ò
or later. A monitor with a resolution of 800 ´ 640 is recommended.
Let the distribution of (X,Y) be a bivariate normal
distribution, i.e. (X,Y) Î
N(mX,mY,sX2,sY2,
rXY)
where rXY
is the correlation between X and Y. The program BIVAR1c calculates probabilities
for the following five events in a given bivariate normal distribution:
1.
P(X £
x and Y £
y)
2.
P(X £
x and Y ³
y)
3.
P(X ³
x and Y ³
y)
4.
P(X ³
x and Y £
y)
5.
P[(x1 £ X £
x2) and (y1 £
Y £
y2)]
