The concept of cost efficiency was introduced by Farrell (1957) as the ratio of factor minimal cost to the actual cost. Unlike technical efficiency, the cost efficiency measure takes into consideration changes in input mix also. The Farrell cost efficiency measure was extended by Fare et.al (1984) for the case of multiple inputs and outputs. Solving one linear programming problem for one production unit, the factor minimal cost can be calculated which is called in this study as 'Farrell Cost Efficiency'. This is a very restrictive measure since it requires the knowledge of input prices and...

India was the first country to start a systematic development of long range forecasting techniques for estimating in advance the seasonal monsoon rainfall over the country. For forecasting rainfall on the basis of past values, a variety of time series models are available these are referred as Box-Jenkins methodology Box and Jenkins.Chief objectives of this book is many folds as listed as to compare and predict the nature of rainfall in three taluks of Khammam district using various statistical methods; Critically comparing the behavior of rainfall in Sathupally, Vemsoor and Aswaraopet taluks...
