   > @zhiqiang-hhhh I compared the data in the test_regr_intercept.out file 
with that in https://dbfiddle.uk/MmKrIU9r, and it seems that there is nothing 
wrong. Can you provide more detailed information?
   
   The reason test_regr_intercept is correct is that I re-write the 
implementation of regr_itercept in that PR (I created that pull request on your 
branch to give you an example on how to fix regr_itercept).
   
   You can compare the code I submitted with your implementation of 
regr_itercept, and do fix on regr_slope in a same way.
