### How to find the number of observations used in the SMARTPLS?

Posted:

**Tue Jan 31, 2017 12:15 pm**Hello everybody,

I estimated the Path Model using Casewise deletion method as the missing value are more than 5% for the indicators. But, i get biased results. Case wise deletion definition says that any observation that has a missing value is not considered at all in the analysis. If this definition is true, my observation ( around 1447 ) will reduce to just 147, because only 147 obseravtions are without any missing value. Could you please tell me if i was right in comprehension of the definition of Case wise deletetion?

The 147 observations mentions above was calculated by me in the CSV file using the function = countif(range, "-99"), after each observation to find out the number of missing values per observation.

Is there an option in the SMART PLS to find out how many observations have been used while executing the PLS algorithm.? . This info will help me to see how many observations have been actually used by the SMART PLS in Case wise deletion method.

I estimated the same path model using mean value replacement method. I got good results. What is your suggestion on which method to use for my analysis?.

Regards,

Aditya
