Cdf Definition and 108 Threads

I ran across this identity in some actuarial literature: Pr( (x_1 \le X \le x_2) \ \cap \ (y_1 \le Y \le y_2) ) = F(x_2, y_2) - F(x_1, y_2) - F(x_2, y_1) + F(x_1, y_1) First of all, I am not certain this is correct. I think the expression on the LHS is equal to the following double...

halw could anyone help me in writing this project in MATLAB ?? A random variable X is observed at certain experiment. 100,000 samples of this random variable are stored in a vector called samples. 1. Use MATLAB to read the samples of this random variable. To read these samples you...

Hi guys, i would like if people can tell what is the maximum probability value that a cumulative density function (cdf) can have? i have been confused by the definition... however i have come to think that the maximum will be 1.. because all events can only be between 0 to 1 (100%) chance...

I was looking at this event display from CDF on their discovery of ZZ production. Why is lepton 1 having an ambiguity of either an electron or muon ? http://fcdfwww.fnal.gov/physics/ewk/2007/ZZ/evd/r211311_e233113.html

Homework Statement Let X represent the random choice of a real number on the interval [-1,1] which has a uniform distribution such that the probability density function isf_{X}(x)=\frac{1}{2} when -1\leqx\leq1. Let Y=X^{2} a. Find the cumulative distribution F_{Y}(y) b. the density function...

How do I find PMF if I have CDF? For example: F_X (x)=\left\{\begin{array}{cc}0,&\mbox{ if }x\leq -1 \\0.2, & \mbox{ if } -1\leq x < 0 \\0.7, & \mbox{ if } 0\leq x < 1 \\1, & \mbox{ if } x \geq 1 \end{array}\right.

I"m not understanding CDF... My textbook doesn't seem to give enough information on it. I"m not understanding what do to when involved with CDFs in general. So if I want to convert a pdf to cdf, given a function fy(Y) = 0 for y <0 2y for 0 <= y <= 1/2 6 - 6y for 1/2 < y <= 1 0 for...
