Geometric Mean Length of Stay

The geometric mean reduces the effect of very high or low values (outliers), which might bias the mean if a straight average (arithmetic mean) is used. Geometric mean is typically used to represent an average rate of growth (which can compound over time) or for differences among data points which are logarithmic (vary by multiples of 10). For lengths of stay GMLOS is calculated by
