Dear all,

When I run the example code of didregress,I get very different result from Stata.com Difference-in-differences (DID) and DDD models | New in Stata 17,
Code:
webuse hospdd
didregress (satis) (procedure), group(hospital) time(month) wildbootstrap(rseed(111)
> )
computing 1000 replications

Finding p-value
.................................................. 50%
................................................. 100%
Confidence interval lower bound
.....
Confidence interval upper bound
............

Number of groups and treatment time

Time variable: month
Control:       procedure = 0
Treatment:     procedure = 1
-----------------------------------
             |   Control  Treatment

                                                       Replications    = 1,000

Here the coefficient is 0.8479,t value is 26.41.But in Stata.com,the coefficient is 0.8601,t value is 19.72.What's wrong with this?
