autoStdAnylsis: Run statistical tests according to OECD guidelines

In StatCharrms: Statistical Analysis of Chemistry, Histopathology, and Reproduction Endpoints Including Repeated Measures and Multi-Generation Studies

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)

Arguments

Data	A data set.
Response	The name (as a string) of the response variable.
TreatmentVar	The name (as a string) of the treatment variable.
Transform	The name (as a string) of the transformation of the response variable. Can take on the values of c('Transformation', 'None', 'Log', log+1', 'Square_Root', 'Arcsin', 'Rank').
WeightsVar	The name (as a string) of the column containing the ANOVA weights.
TimeVar	The name (as a string) of the Time variable.
TestDirection	The direction of the hypothesis test. Can take on any of the values of: c('Decreasing', 'Increasing', 'Both').
ReplicateVar	The name (as a string) of the replicate variable.
AlphaLevel	The alpha level used in the Jonckheere-Terpstra test for trend. See (jonckheereTerpstraTest).

Value

See the following function for details on the analysis.

Jonckheere	Jonckheere-Terpstratest test see jonckheereTerpstraTest.
Dunns	A Dunns test see dunnsTest.
Dunnet	A Dunnet test see oneWayDunnettTest.
