VerifyTestAssumptions

VerifyTestAssumptions
is an option to LocationTest and similar functions that controls which assumptions to verify through diagnostic tests.
MORE INFORMATION
  • The following settings can be used:
Allverify all assumptions
Automaticautomatically select which assumptions to verify
Nonedo not verify assumptions
"name"verify the named assumption
{"name1","name2",...}verify several assumptions
  • The specific list of assumptions that can be verified through diagnostic tests is given for each hypothesis testing function.
EXAMPLESCLOSE ALL
Basic Examples   (3)
Control diagnostics as a group using All and None:
The -value is equivalent but a warning is issued:
Set diagnostics independently:
Testing for normality results in a warning being issued:
Normality is assumed but a test for equal variances chooses a different form of the -test:
Turn off diagnostic testing for simulation purposes:
The results are identical:
