Help with table interpretation I am an agricultural genomics student and I need help understanding this table of statistics from a study of 1340 cows. can you please explain to me what it means when the mean value is 0? and how to interpret its standard deviation in this case?


A mean of 0 means that on average the effect of your variable REI1 and REI2 is 0. But the standard deviation comes from the fact that for each sample this effect may differ from zero. See the image below for an illustration.
