Management > Managerial Statistics > Index Number By Kelly’s Method and Walsh’s Method Kelly’s Method: Truman L. Kelly has suggested the following formula for constructing index number. Here weights are the quantities which may refer to some period, not necessarily the base year or current year. Thus the average quantity of two or more years […]

No Comments on Marshall Edgeworth Method

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 […]
