    Mean waiting time due to aggregation of k poisson arrivals

    Dear Experts: I want to calculate the mean waiting time due to aggregation of k arrivals following poisson process with rate #λ#. Arrivals are served in chunk i.e., if N arrivals reach buffer, OR deterministic timer T expires. The timer ALWAYS starts at the first arrival. So, first arrival reach...

    Kernel Density Outlier Threshold

    Hi All, First of all, thanks for showing an interest in this thread, and secondly, if your so kind to give your thoughts, I'd be so grateful. Background - We work with financial bank statements for fraud investigation. - I have converted a bank statements debit transactions into a scatter...

    Density probability of a normal distribution at a point in a CASIO calculator

    I do not understand the utility of calculating the density probability in a point in the case of a continuous variable (for example in the case of the normal distribution). Some CASIO calculator include a function ("normal P. D.") which calculate the value of the density function of normal at a...

    Searching for a probability distribution where expected value is zero.

    Hi, I am working on an agent based model. And, in the model every agent has an action. The action leads to a certain pay-off. The assumption is that the agent is not aware of all the actions but only the pay-off generated. Hence, in order to know what payoff an action will generate, the agent...

    Probabilities from Distribution Functions

    Buses arrive at fifteen minute intervals starting at noon. Anne arrives at the bus stop X minutes after noon, where X is a random variable with distribution function FX(x) = P(X ≤ x) = 0 for x < 0, x2 /3600 for 0 ≤ x ≤ 60, 1 for x > 60. (a) What is the probability that Anne waits less than...

    I'm confused on probability density functions - please help!!

    These questions are from a sample test, I don't know how to do them. Obviously there's a lot of questions so I'm not expecting people to do them for me, just telling me HOW to do them would be amazing. Any help would be extremely appreciated! 1) If P(X) = P(Y), the random variables X and Y are...

    summing two probability density functions---Gompertz hazard model?

    Hi, r-help members. I have a question about summing two density distributions. I have two samples from which I've estimated hazard parameters for a Gompertz mortality model. With those parameters, I can calculate the PDF (survival function times hazard function) of ages-at-death in a birth...

    probability distribution

    Hello All, I calculated an average latency value let say 3 units then after observing the network I found that different nodes have the fallowing differnt latency i.e. 4, 5, 6, 7, 10 units. now I need to assign probability to each latency considering that the value which is more closer to...

    x2 Probability function

    Hello, I have a rather basic question, but enough to raise me some doubts. Let's give the practical example. In a factory, we have a device that is constantly used and has a failure probability function f(x), where x is the number of times the device is used. f(x0 here is a monotonic...
