Title: Equivalence Test for the Means of Two Normal Distributions
Authors@R: person("Chao", "Wang", email = "wan9c9@gmail.com", role = c("aut",  "cre"))
Description: Two methods for performing equivalence test for the means of two (test and reference) normal distributions are implemented. The null hypothesis of the equivalence test is that the absolute difference between the two means are greater than or equal to the equivalence margin and the alternative is that the absolute difference is less than the margin. Given that the margin is often difficult to obtain a priori, it is assumed to be a constant multiple of the standard deviation of the reference distribution. The first method assumes a fixed margin which is a constant multiple of the estimated standard deviation of the reference data and whose variability is ignored. The second method takes into account the margin variability. In addition, some tools to summarize and illustrate the data and test results are included to facilitate the evaluation of the data and interpretation of the results.

Description: Provides a consistent vector representation of years with an
associated calendar era or time scale. It includes built-in definitions of
many contemporary and historic calendars; time scales commonly used in
archaeology, astronomy, geology, and other palaeosciences (e.g. Before
Present, SI-prefixed 'annus'); and support for arbitrary user-defined eras.

Description: Provides a consistent representation of year-based time scales as a
numeric vector with an associated 'era'. There are built-in era definitions
for many year numbering systems used in contemporary and historic calendars
(e.g. Common Era, Islamic 'Hijri' years); year-based time scales used in
archaeology, astronomy, geology, and other palaeosciences (e.g.
Before Present, SI-prefixed 'annus'); and support for arbitrary user-defined
eras. Years can converted from any one era to another using a generalised
transformation function. Methods are also provided for robust casting and
coercion between years and other numeric types, type-stable arithmetic with
