To make the SEM more informative we can convert it to a confidence interval. To calculate the standard error of the mean in a sample, the user needs to run a one-line command in Matlab "stderror = std( data ) / sqrt( length( data ))", How do I add an item to my watch list? So I tried stats = regstats(Y,X,'linear').

- It came out another error message " Too many output arguments." I did use vector for Y and X,not including a column of ones.

The coefficient variances and their square root, the standard errors, are useful in testing hypotheses for coefficients.DefinitionThe estimated covariance matrix is∑=MSE(X′X)−1,where MSE is the mean squared error, and X is the A common reason people calculate the SEM is to create error bars for bar charts.
