PLS-Quality Criteria-Overview- Redundancy negative value

Post by M Ashok » Mon Jul 15, 2013 10:50 am

Dear Moderators
I have run the model in SmartPLS and read the FAQ top Posted: Mon Oct 15, 2012 3:44 am Post subject: What is 'redundancy' in quality criteria?
Sarjana Hengky Latan

However, SmartPLS default report PLS-Quality Criteria-Overview shows a negative redudancy for one of the constructs. I have pasted the table below, althought it has lost indentation.

Please suggest how do I gather the correct value for the construct PI below.

Thank you
Mona

Hi
You probably use unstandardized data, which you should not use – we commented on this issue elsewhere in this forum. Use standardized data when starting the PLS algorithm (see algorithm settings).

Dear Prof. Ringle
I checked the setting and I have selected the default option of mean 0, var 1. However I continue to get a negative redundancy value. Please suggest next steps.

Thank you.

Hi

Can't be... If you mean this value, "-0.0004", consider it as being zero (the negative outcome is a results roundings). Otherwise, manually compute the redundancy for your results and send me the Excel spreadsheet so that I can have look.

Best regards,
