They are symmetrical and provide close approximations of The change in a Fisher index from one period to the next is the The Törnqvist or Törnqvist-Theil index is the geometric average of the n price relatives of the current to base period prices (for n goods) weighted by the arithmetic average of the value shares for the two periods.The Walsh price index is the weighted sum of the current period prices divided by the weighted sum of the base period prices with the geometric average of both period quantities serving as the weighting mechanism:

On the other hand, a formula such as 2*INDEX(A1:B2,1,2) translates the return value of INDEX into the number in cell B1. A number of different formulae, more than hundred, ... Price index numbers are usually defined either in terms of (actual or hypothetical) expenditures (expenditure = price * quantity) or as different weighted averages of price relatives (/).

Steps Involved: Denote prices of commodity in the current year as P 1 and its quantity consumed in that year by Q 1. Price relative refers to the percentage ratio of the value of a variable in the current year to its value in the year chosen as the base.Here, P1= Current year value of item with respect to the variable and P2= Base year value of the item with respect to the variable. They took as 4*. The Kelly formula (edge/odds), in expanded form, is: (P*W-L)/P. For example, when calculating the price index number if the price of a unit of rice is twice the price of a unit sugar then the rice will be weighed in as ‘2’ whereas sugar will be weighed in as ‘1’.Hence it is a relatively average measure. 2] Simple Aggregative Method. Larger the sample size more is the accuracy. Have a doubt at 3 am? 4 1927), where he recognized that no index number would satisfy all the desired properties, but he chose the geometric mean of the Laspeyres and Paasche indices as his ideal index number formula.
