Array like this: A=[1 2 1 1 0 2 2 0 0 2 1 0 2 1 1 0 0]; How to sum every number between each zero occurence like this: B=[5 0 4 0 0 3 0 4 0 0]; And I also want to remove the zeros from B so I will end up with: ...
it holds % that a_OLS = vec(A_OLS) SSE = (Y - X*A_OLS)'*(Y - X*A_OLS); % Sum of squared errors SIGMA_OLS = SSE./(T-K+1); % Initialize Bayesian posterior parameters using OLS values alpha = a_OLS; % This is the single draw from the posterior of alpha ALPHA = A_...
