Default is 0 which means you test for equality of parameters. Currently there are no other options. If you change the value, it will still test for equality (0)} } \value{ a dataframe with the test statistics } \description{ Use this test if you estimate the exact same model with different data sets. For example, if you have a split sample and want to compare the two samples for differences in preferences. The test is especially useful for models in WTP Space where the Poe Test ist not adequate. } \examples{ \dontrun{ apollo_ztest(model1,model2) } }
