assert/check/test/Symmetric

Validation checks to test if Distribution is symmetric.

testSymmetric(object, errormsg = paste(object$short_name, "is not symmetric"))

checkSymmetric(object, errormsg = paste(object$short_name, "is not symmetric"))

assertSymmetric(
  object,
  errormsg = paste(object$short_name, "is not symmetric")
)

Arguments

object

Distribution

errormsg

custom error message to return if assert/check fails

Value

If check passes then assert returns invisibly and test/check
