Management > Managerial Statistics > Index Number By Marshall Edgeworth Method The Marshall Edgeworth Method for the index number, credited to Marshall (1887) and Edgeworth (1925), is a weighted relative of the current period to base period sets of prices. This index uses the arithmetic average of the current and based period quantities for weighting. Price Index by Marshall Edgeworth Method: […]

1 Comment on Fisher’s Ideal Index Number

Management > Managerial Statistics > Index Number By Fisher’s Method Laspeyre’s method is based on fixed weights of the base year. For price index base year’s quantities are used as weights. Paasche’s method is based on fixed weights of the current year. For price index, current year’s quantities are used as weights. Fisher has suggested […]

Lapeyre’s Index Number

Management > Managerial Statistics > Index Number By Larpeyre’s Method When all commodities are not of equal importance, we assign a weight to each commodity relative to its importance and the index number computed from these weights is called a weighted index number. For example, when calculating the price index number if the price of […]
