The efficiency of prediction of mean gravity anomalies for areas of 1 degree x 1 degree, 2 degree x 2 degree, 5 degree x 5 degree, and 10 degree x 10 degree from known mean anomalies is studied. The least standard prediction error is found to be about 12 var 12 where var is the variance of mean anomalies. The influence of the nearest neighbors is prevailing. The prediction from many known anomalies is about the same as from only a few known values. Author
