Hello,

I'm trying to plot a F PDF as seen at the bottom of this link: http://www.mathworks.com/help/stats/f-distribution.html

I'm using excel 2007.
X Axis: I have a column for the positive real number domain including zero, in increments of .01, looks something like this...
A1:X
A2:0
A3:0.01
.
.
.
A1001:10

Y Axis: I tried using the formula =FDIST(A2,5,3) to compute the y axis values, but my values are very different than the mathworks' site.

B1:Y
B2:1
B3:0.99993
.
.
.
B1001: 0.043419

Just from plotting the graph, I can tell that something is not right, the shape is not the same as the example, and the mathwork's graph doesn't have any y axis values over .6.

Why does the excel f distribution PDF look different? Why does it have a .999?

Please advise on what approach I should take to reproduce the results on the mathworks site.

Thanks!
