Hello Prof,
When I calculate the Person correlation, there are data as follows:
Burundi BDI 2014 831.29486 10494920 5.3740325 59.9 2.905
Burundi BDI 2015 781.5793 10727153 4.2975073 60.2 2.905
Burundi BDI 2016 764.3366 10903329 5.82391 60.8 2.905
As we can see, the Cantril is all the same, thus the denominator will be zero. Should I ignore this country and report the error?
Cheers

Hi Zeke,
This is not an error. The data is valid; the Cantril values just happen to be the same. (Perhaps they asked the same person each year??😉). In any case, from the point of view of data cleaning, it is clean data, and for this analysis, all you can do is ignore it for the calculation, but perhaps comment on stderr as it is unusual.
Cheers
