I'm trying to extract the model parameters using:
clc
clear all
data = xlsread('cancer_train.xlsx');
X = data(:,1:9);
Y = data(:,10);
mdl = fitcnb(X,Y);
mu=[];
[m,n] = size(data);
for i = 1:m
mu(i,1) = mdl.DistributionParameters{1,i}(1);
end
I get index out of range after element 9! The excel can be found here: http://dropcanvas.com/#S47z19vg5WISRQ

According to the code, what you pick, the loop should run till 9 only.
clc; clear all ;
clc
clear all
data = xlsread('cancer_train.xlsx');
X = data(:,1:9);
Y = data(:,10);
mdl = fitcnb(X,Y);
% [m,n] = size(data);
m = size(mdl.DistributionParameters,2) ;
mu = zeros(m,1) ;
for i = 1:m
mu(i,1) = mdl.DistributionParameters{1,i}(1);
end

That's not what I want, I want to get the mean of all features whose class is 1. I guess the first 9 ones are 1, that's why it stops? Any suggestions to work around this problem? perhaps an "if" to check if the class is 1, but what is the m?
Edit upon looking at the data, the first 9 ones are mixed, why the heck is it stopping after just 9?!
Edit: ohhh the i is the feature number?!!!
