    Poisson Distribution Model Έχει λήξει left

    I need someone to build me a model in excel (preferably) where I can input 3 variables. The model will then produce two series of random variables with a Poisson Distribution. Variable Input 1 - Mean of Poisson Distribution 1(X) Variable Input 2 - Mean of Poisson Distribution 2 (Y) Correlation coefficient Input - Correlation between Poisson Distribution 1 and Distribution 2 Once these three inputs are changed the output of the two random Variables X & Y will change. I need about 30,000 random variables for each X & Y. The correlation between the two - (the third input) - has to be allowed to be either negative or positive. See attached a spreadsheet showing required inputs and outputs.

    Software Project in Optimization Έχει λήξει left

    The project consists of two phases. In the first phase, you are required to write a program that can calculate all the roots, including the complex ones, of a polynomial Pn(x) of positive integer degree n and the coefficient a0 of xn is positive. The solution method is recursive, which means it will break down the problem into smaller sub-problems until it can solve them easily. The recursive solution method has the following steps: Step 1: If the degree of the polynomial Pn(x) is less than or equal to 4, use the solve_p4c.c program to find the roots. Step 2: If the degree of the polynomial Pn(x) is odd, find a segment (a,b) where Pn(a)Pn(b) < 0. You can calculate Pn(0) to determine which value to use for a and b. Then use the bisection method or the bisection method with regu...
