However, with R12 you can also use GLMFIT to get SEs for a linear model: >> x = (1:25)'; >> y = 1 + 2*x + randn(25,1); >> >> [beta,dev,stats] = for i=1:n s0 = s0 + (h(i)- M)^2; %// add each calculated s0 to its previous value.

So the 95% confidence limits are: data=randn(1,30); sem=std(data)/sqrt(length(data)); % standard error of the mean sem = sem * 1.96 % 95% confidence interval sem = 0.3553 If you know the appropriate Structural Equation Modeling Matlab Join the conversation recipes : Statistics : Calculating the standard error of the mean Problem How do I calculate the standard error of the mean in MATLAB?? How would you help a snapping turtle cross the road?
More specifically, the SEM is the theoretical standard deviation of the sample-mean's estimate of a population mean.
- You can add tags, authors, threads, and even search results to your watch list.
- Next, the user can calculate the standard error of the mean with the command "stderror = std( data ) / sqrt( length )".
