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 geometric mean, sometimes referred to as geometric average of a set of numerical values, like the arithmetic mean is a type of average, a measure of central tendency. Due to the formula used to calculate it, all values in the dataset must have the same sign, that is, they must be all positive or all negative.
