Formula for calculating bootstrap tvalue
Formula for calculating bootstrap tvalue
What is the formula used for calculating the bootstrap tvalue? I have done a bootstrap with 1000 replicates, and if I use the 1000 estimates for one of the coeffiecients and calculate the tstatistic for the hypothesis that the coefficient=0, (mean divided by stdev divided by root of 1000) then I dont get the same as calculated by SmartPLS. What I am doing here in any case does not make much sense because of the large "bootstrap sample size" the test is based on.

Dear Dr. Kidd,
the formula for the tvalues is as follows:
t = beta / stdev_bootstrap(beta)
You have to keep in mind that the standard deviation of the bootstrap estimates is equivalent to the standard error of the original parameter estimate. Thus, there is no need to divide by SQRT(1000).
Hope this makes sense,
Stefan
