I have no idea how to write in Python. Please help me with this! Best answer if you write the program! Central Limit Theorem I Goal Write a python program that will use your accept / reject Monte Carlo algorithm to demonstrate the central limit theorem. Recall: The central limit theorem states that if s = ∑j=1 N xj (ie. s is a sum of M random variables x1, ..., xM), then the distribution of s approaches a Gaussian distribution as M increases. Here the index j is being used to indicate different variables. Furthermore, the mean of the resulting … |

Hey guys I'm having trouble figuring out how to calculate the standard divination of an array in Java. As you can see I have already calculated the mean, and I know that at the end I will have to divide by the sample size minus 1 (n-1) and square that number. The problem I'm having is how to take every number and calculate how far it is away from the mean, then square that number. I know I could do every number from the data set separately but there has to be an easier way. Any help would be appreciated, … |

Hello, I'm fairly new to python and I've currently run into a road block in this problem. I set up this code: def average(the_list): return the average of the list def deltalist(the_list,a): return a list which is each of the element of the_list subtracted by a def squarelist(lst): return a list which is each of the element of the_list squared def variance(the_list,mean): return squarelist(deltalist(the_list,mean)) def stddev(l): a = average(l) l3 = variance(l,a) return math.sqrt(sum(l3)/(len(l3) - 1)) lst = [1,3,4,6,9,19] print(stddev(lst)) the `return` statements is the problem I've ran into. I want to implement the average, squarelist, and the delta list … |

hi i'm making an excel worksheet that will generate some random numbers. i used this formula: =RAND()*(High-Low)+Low, to generate a number between 0 and some other value and then subtract that from another number. Like this i obtain random variations around a value(just lower than the original). However, i need these numbers to vary by a given value. (the maximum difference between consecutive values to be given by the user) can anyone tell me if this can be done with excel(and if yes how;)) or do i have to get into VBA? If no, and i have to write code, … |
