Harmonic mean index
WebIn mathematics, the geometric–harmonic mean M(x, y) of two positive real numbers x and y is defined as follows: we form the geometric mean of g 0 = x and h 0 = y and call it g 1, i.e. g 1 is the square root of xy.We also form the harmonic mean of x and y and call it h 1, i.e. h 1 is the reciprocal of the arithmetic mean of the reciprocals of x and y.These may be done … WebDec 1, 2024 · Simlarly to this post: efficient function to find harmonic mean across different pandas dataframes I have two Pandas dataframes that are identical in shape and I want to find the harmonic mean of each pair of elements - one from each dataframe in the same location. The solution given in that post was to use a Panel, but that is now deprecated.

They do not make any use of quantities or expenditure weights. They are called "elementary" because they are often used at the lower levels of aggregation for more comprehensive price indices. In such a case, they are not indices but merely an intermediate stage in the calculation of an index. At these lower levels, it is argued that weighting is not nece…
