system variation

[ArnoStrouwen]

On ubuntu:

 random slope: Test Failed at /home/runner/work/KenwardRoger.jl/KenwardRoger.jl/test/random slope.jl:90
  Expression: isapprox(res[!, "StdErr"], sw.m.stderror, atol = 1.0e-5, rtol = 1.0e-5)
   Evaluated: isapprox([7.9073852566, 4.0763028478, 0.4158793339], [7.907532440848217, 4.076212605378292, 0.4158688334987205]; atol = 1.0e-5, rtol = 1.0e-5)

While on windows this test passes:

julia> sw.m.stderror
3-element Vector{Float64}:
 7.907442352018266
 4.07628014673138
 0.4158775080796224

What causes this sytem variation?

My guess is differences in the LLVM compiler, as ubuntu probably uses Clang and windows MSVC. Did you use SAS from windows to get the test data?
