Second order vs First order calculation error

Post by maniesa1478 » Sun Nov 05, 2017 11:37 am

My current framework is similar to the below link. The author uses SmartPLS 3.0 to calculate the data.

Notice that 'Airport Physical Environment' is the 2nd order variable for the 4 variables (layout, facility, functionality, cleanliness). Airport Physical Environment is without any indicators. https://www.screencast.com/t/qk4vg0ZkefiE

However, when I applied the same framework, I received error 'there must be a valid pathmodel for calculation'. What did I do wrong with my model?

How did the other scholar managed to calculate and I can't? Appreciate anyone help.

Thank you

All constructs need indicators in PLS. Therefore you need to use approaches that try to identify the second-order constructs, which are usually either the repeated indicator approach or the two-stage approach.

You can find information on this issue in the following publications:
