Hi Svend,
Thanks for the tip! I accidentally left the duration variable as
float, which means that some individual experienced the even in .5
year while others in .2 year. After rounding the variable, I
eliminated all the abnormal values.

Why is it that you would consider a non-integer duration abnormal?
