Choice of elective courses in IIMA: an application of factor analysis
Raghavachari, M. (2010-03-14)The report is based on a study made to find the factors influencing the choice of elective courses by the second year students of IIMA. The statistical technique of Factor Analysis has been used to identify the factors. -
Determinants of effective working capital management - a discriminant analysis approach
Bhattacharyya, S. K.; Raghavachari, M.; Singh, Arwind Kumar (2010-03-13)Currently, many financial analysts rely on traditional financial ratios for assessing the effectiveness of the working capital management. They correlate corporate performance in this area with the so-called "ideal" ratios. ... -
Deterministic and Random Single Machine Sequencing with Variance Minimization
Vani, Vina; Raghavachari, M. (2012-09-27) -
A geometric programming approach to solve van der waerden conjecture on doubly stochastic matrices
Raghavachari, M. (2010-03-13)In this paper the problem of finding the minimum of the permanent of a doubly stochastic matrix has been formulated as a reversed geometric program with a single constraint and an equivalent dual formulation is given. A ... -
Institution building for management education in India- IIMA experience
Raghavachari, M. (Indian Institute of Management Ahmedabad, 1979-10-01)This paper gives a short factual account of some of the IIMA Experience in institution building for management education. The format of presentation is in line with the conceptual framework of institution building process ... -
Mathematical programming method to determine exact optimum allocation in stratified random sampling
Raghavachari, M. (2010-03-20)In this paper an exact integer programming formulation is proposed and an efficient method of finding optimal solution is given. An alternative method using incremental or marginal analysis approach is also given. A numerical ... -
Necessary and sufficient condition for a matrix to be totally unimodular
Raghavachari, M. (2010-03-13)A characterization of totally unimodular matrix is gives is the paper. This provides an iterative method directly applicable on the matrix itself to recognize total unimodularity or otherwise of any given matrix. -
Note on two - phase method for a class of metric models in individual scaling
Vani, Vina; Raghavachari, M. (2010-03-12)This working paper the authors discuss the typical problem in individual scaling viz., finding a common configuration and weights attached to dimensions for each individual from the given interpoint distances or scalar products. -
On the computation of Hodges-Lehmann efficiency of test statistics
Raghavachari, M. (2010-03-13)An approach to the computation of Bahadur Efficiency was proposed by Bahadur and Raghavachari in their paper in Proceedings of Sixth Berkeley Symposium. The objective of the paper is to exhibit this approach to the Computation ... -
On the number of non - negative integral solutions to the Kanpsack problem
Raghavachari, M.; Sabharwal, Y. P. (2010-03-14)This paper develops expressions for the exact number of solutions to the well known Knapsack problem. These formula are compared with the bounds given by other researchers in this problem. A computer programme has also ... -
Some properties of optimal schedule of jobs with a common due date
Raghavachari, M. (2010-03-13)Kanet (Naval Research Logistics Quarters, 1981) considered the problem of minimizing the average deviation of job completion times above a common due date. Under the condition that the common due date exceeds the makespan ... -
Some results in finding a lower bound of the efficiency of least square estimates relative to best linear estimates in regression model
Raghavachari, M. (2010-03-15)Consider the usual regression model Y = X? + ?. The standard estimators of ? are (i) Least squares estimator and (ii) Best linear estimator. The paper gives some results on finding an attainable lower bound on the efficiency ...
