Question
Why does my random walk simulation come out so weird?
Why does my graph come out so weird? I've provided the code: clearvars N = 1000; M = 500; P = cumsum(full(sparse(1:N, randi(...

Confused how to run a loop for each individual value of Nd1?
Nd1 = [5, 10, 50, 100, 500, 1000]; trials2 = 100; sigma = 4; samplevar = zeros(Nd1,1); samplevarbias = zeros(Nd1,1); for i...

Monte Carlo method to estimate pi, but I'm lost
Nd2 = [10, 100, 1000, 1e4, 1e5, 1e6]; % vector of sample sizes. pihat = zeros(size(Nd2)); % vector to contain the estimates of ...

Why is my code not working? I'm supposed to determine the mean of a biased and unbiased sample variance and plot but it's not working
%% 1. Sample variance bias Nd1 = [5, 10, 50, 100, 500, 1000]; trials2 = 100; sigma = 4; samplevar = zeros(length(Nd1),trial...

I'm definitely doing the exponential distribution wrong, am I?
N = 1e4; a=0; b=1; x = a+(b-a)*rand([N,1]); lambda = 1; Y = -log(x)/lambda; figure(1); clf histogram(x,20,'Normalization',...

Why are my Gaussian distributions not properly being generated?
N1 = 1e4; Y1 = randn(N1,-5,4); % N2 = 1e4; Y2 = randn(N2,5,3); N3 = 1e4; Y3 = randn(N3,0,5); figure(5); clf histogram(Y3...

Need help finding out if I wrote this code correctly
N = 365; n = (1:80); for M = 1:1000 j = (1:n); pn = 1-(1-((n-1)/N)); end %% fig = figure(1); clf plot(pn) xlabe...
