Hi,
I'd like to know the default value of the significance level, but
can't find it.
Could someone please tell me what the vaule is and how to change it?
Another question is that the tstatistics in the bootstrapping output are based on the 2sided t test?
Thanks.

Hi Aden et al.
Sorry, but I'm not sure I fully understand your question(s).
The bootstrapping procedure in SmartPLS produces tvalues for many of the parameters/ estimates of your model (e.g., loadings, weights or path coefficients). These tvalues are your raw input for running significance tests. However, PLS doesn't run those for you. You have to do it yourself.
Testing a path coefficient for significance works like this:
1) Decide on your desired alphalevel (e.g., 0.05)
2) Decide on a one or twosided test (depending on your hypothesis for the path)
3) Look up the critical tvalue in a table using the number of boostrap runs (e.g., 1000) as the degrees of freedom
Examples:
a) For a onesided test on significance at the 0.05level with 1000 bootstrap runs your bootstrapped tvalue should exceed 1.646 (or 2.330 at 0.01level).
b) For a twosided test with the same parameters the bootstrapped tvalue has to exceed 1.962
Hope this helps.
Cheers,
Stefan
