i hope someone can help me with this. i have finished a computer science
study that examines swarming behavior. my claim is that the swarming
algorithm that i use produces a gaussian distribution - on a grid, the
frequency that each area is visited is recorded. graphs of my data looks
like there

Visualize a large cubic room, say 100 feet on a side. 1,000 ping pong balls
will be removed from an urn and placed in the room via random drawings from
a uniform distribution for the x, y, and z position. The balls will be held
stationary in their assigned position by means of magic. Once all
Hi everyone,
we just leanred the cov, and I'm trying to apply the formula
cov(X,Y)=E(XY)-E(X)E(Y) to the following question
f(x,y)=(0.6)^x(0.4)^1-x(0.3)^y(0.52)^1-y(2)^xy where poss. values for X and
Y are x=0,1 and y=0,1.
The prof. never gave us any examples for cov and neither does the text
here is one VERY simple example
the COV is the AVERAGE of the PRODUCTS of the deviations around the means
... of two variables
if the cov is + .. there is a + relationship between X and Y, if it is -,
there is a - relationsip between X and Y
X Y devX devY (devX)(devY)

Hi everyone, I have this problem and I was
wondering whether anyone can help me.
I have data on the number of accidents occuring on
two different roads, two different years,three different time periods
(of unequal length), given a number number of vehicles
for each occasion. (for example,
is there somewhere i can go on the web to learn about things such as
probability distributions (binomial/bernoulli trials, poisson,
normal), statistical estimation (confidence intervals, etc), sampling
distributions (t, chi-square, f), hypothesis testing, analysis of
variance (ANOVA). hopefully
