Hi,

yes it does - in the new version SmartPLS 2.0 M2!

You need to indicate MVs (e.g. by "-999") before importing data into SmartPLS. Then use the options to treat MVs in the software application.

Any chance of making the missing data value something other than -999?

It has never happened to me, but I always wonder about someday using some dataset where -999 is a valid potential data value!

Could it become some non-numeric symbol? A period, ala SAS is good, or any others (e.g. !,@,#,$,%,^,&,*).

Just something I've always wondered about in programs that pick -999.

Thanks!

Hi,

Thats a misunderstanding.

Missing values are configured "per datafile" in SmartPLS.

So you can pick any value you want as your indicator for a missing value.

Just use the "Properties" dialogue (right click -> check the context menu) for configuration.

When importing data, I did not get the Missing Value question. I had to adapt it later. Is this right?

The data import wizard contains a next and a finish button. If you enter the name of your data file and then directly hit the finish button, you're indeed done.

The question for missing values appears on the second wizard page that shows up if you hit the next button.

When you import indicator data, a wizard pops up to guide you through the process. Choose "next" at the bottom of the wizard, instead of "finish". On the second screen, you'll see a message entitle missing values settings. Click on the box indicating "the data contain missing values", then fill in the number that you use for missing values (999 or whatever).

Hi,

how does the SmartPLS algorithm handle missing values? How are they imputed? I know that PLSGraph uses a combination of mean replacement and pairwise deletion.

Thanks a lot.

Best regards,
Christian

Edit: Ok, found the options.

Hi,

Does the SmartPLS automatically treat the missing values (such as mean replacement or listwise deletion) ? Or do I need to use other software to treat this missing values?

Can anyone help?

Cheers,
Linda
