Harmonic Mean
Description
Calculates the harmonic mean of a numeric vector, robustly handling special cases.
Usage
harmonicmean(x, na.rm = TRUE)
harmonicsum(x, na.rm = TRUE)
Arguments
x |
Numeric vector. |
na.rm |
Logical value specifying whether to remove |
Details
The harmonic mean of a set of numbers is the reciprocal of the mean of the reciprocals of the numbers.
The function harmonicmean
calculates the harmonic mean
of x
. The algorithm robustly handles special cases
where some of the values in x
are very small or are
exactly equal to zero.
The function harmonicsum
calculates the reciprocal of the
sum of the reciprocals of the x
values.
Value
A single numeric value.
