Hi i have this Page hinkley test
sumPH=0
for t=1:Nt
mew2=(inv(Nt)*sum((y2-xhat2)));
vari2=(inv(Nt-1)*sum((xhat2-mew2).^(2)));
sumPH= sumPH + vv/vari2*(rg12 - mean(mew2) -vv/2);
pp=max(0,sumPH);
end
Now i want to plot (t,pp) using either 1 or zero. How do i coding if i want to make maximum of pp become 1 instead its own value of sumPH ?

You mean normalize the plot?
sumPH=0
for t=1:Nt
mew2 = (inv(Nt)*sum((y2-xhat2)));
vari2 = (inv(Nt-1)*sum((xhat2-mew2).^(2)));
sumPH = sumPH + vv/vari2*(rg12 - mean(mew2) -vv/2);
pp(t) = max(0,sumPH); % save each data point
end
plot(t,pp/max(pp)) % plot normalized data
If you want to plot only 1s and 0s, then you would use
pp(t) = sumPH>0; % save each data point
...
plot(t,pp) % plot data
