Finding geometric mean
WebHere is a vectorized, zero- and NA-tolerant function for calculating geometric mean in R. The verbose mean calculation involving length (x) is necessary for the cases where x contains non-positive values. gm_mean = function (x, na.rm=TRUE) { exp (sum (log (x [x > 0]), na.rm=na.rm) / length (x)) } WebThe GEOMEAN function calculates the geometric mean of a set of numbers by returning the nth root of n numbers. Hence, the Geomean of 30000 and 33000 is calculated as: = (30000*33000)^ (1/2) =31463.3. The arithmetic mean would be (30000 + 33000)/2 = 31500.
