I'm currently trying to use glmfit like this:
B2 = glmfit(x(c,:),y,'binomial');
With y being a n x 1 matrix with 1's and 2's for group one and two. However, it keeps giving me the following error:
For the binomial distribution, Y must be a binary vector or a matrix with two columns with the number of trials in the second column.
My question is: Should I ad a second column with 1:number of observations? Example below:
y = [1,1; 1,2; 1,3; 1,4; 2,5; 2,6; 2,7; 2,8];
