autoStdAnylsis: Run statistical tests according to OECD guidelines

Description

Runs tests following the flow chart outlined in the OECD guidelines for the tier II tests for endocrine disruptors. The basic outline of the flow chart is as follows: 1) if the data is monotonic run a jonckheere Terpstra trend test, 2) is the data is not monotonic but is still normally distributed, run a Dunnett's test, 3) if the data is not monotonic and not normally distributed run a Dunns test.

Usage

autoStdAnylsis(Data, Response, TreatmentVar, Transform, WeightsVar, TimeVar, 
TestDirection, ReplicateVar, AlphaLevel)
