Hi Everyone,
I would like to assess the structural model via path coefficients. The bootstrap re-sampling technique (Chin,1998) was used by 500 iterations of the original 248 samples.
After finished the BT analysis, I got the HTML Report as below:
My Question is, Which one of the report in that table of content suitable for checking path coefficient significance?. Do I need to calculate t-statistics = path coefficient / S.E?, for testing significance at p<0.05,p<0.01 or p<0.001.
which column shows the path coefficient
Thanks

Hi Brisbane,
You should notice that the table “Path coefficients (Mean, STDEV, t-Values)” has these columns: Original Sample (O), Sample Mean (M), Standard Deviation (STDEV), Standard Error (STERR), T Statistics (|O/STERR|).
The first column has the path coefficients that were computed with all sample, they are the same values when you ran the PLS algorithm.
The last column are the t-values (t > 1.96 are significant at 5%), these values are showed in the model too.
The others columns are intermediate calculations to have the t-value in the last column.
Best regards,
Bido

Dear Prof. Bido,
Many thanks for your advice. I'm really appreciating it.
Yes, just realized that the t-value calculated as the same t statistics from Z population, according to basic statistics.
t= sample/S.E
How to calculate p-value? from coeff. table?
How about degree of freedom?, I found it via this URL

Hi,
d.f. = n - 1 (n = number of resamples in the bootstrap)
you could use the p-value calculator that you had quoted
or Excel --> see viewtopic.php?p=3797&highlight=#3797
