Confidence Intervals for t-tests

A common test performed when looking for dysregulated metabolites is a t-test. However, metaboanalyst fails to provide confidence intervals for these tests. Thus, this tool provides confidence intervals for each metabolite tested.

Formulation

$$ CI = \bar x \pm z\frac{x}{\sqrt{n}}$$

where, $\bar x$ is the sample mean of data object, z represents confidence level, s is the sample standard deviation, and n is the sample size.
