testing significan linier trend

21 views (last 30 days)
If I want to find out whether or not there is a significant non-zero trend in these data, would I use the regress(y,X) function? Here's an example of what I'm doing:
if true
% code
load Tmks.txt
time = Tmks (:,1);
suhu = Tmks (:,2);
alfa= 0.05;
[b,bint,r,rint,stats] =regress (time,suhu,alfa);
X = ones (size(time));
[b,bint,r,rint,stats] =regress (time,suhu,alfa);
how to get the significant trend ? thank you

If you are using a version equal to or later than 2013b than you can use the fitlm function which prints the relevant t-statistics.
