Finding standard error of estimate
WebWhere: s = sample standard deviation x 1, ..., x N = the sample data set x̄. = mean value of the sample data set. N = size of the sample data set WebDec 4, 2014 · The standard error determines how much variability "surrounds" a coefficient estimate. A coefficient is significant if it is non-zero. The typical rule of thumb, is that you go about two standard deviations above and below the estimate to get a 95% confidence interval for a coefficient estimate.
