In mathematics, the ratio test is a test (or "criterion") for the convergence of a series =, where each term is a real or complex number and a n is nonzero when n is large. The test was first published by Jean le Rond d'Alembert and is sometimes known as d'Alembert's ratio test or as the Cauchy ratio test.
Liquidity ratios measure the availability of cash to pay debt. [2] Activity ratios measure how quickly a firm converts non-cash assets to cash assets. [3] Debt ratios measure the firm's ability to repay long-term debt. [4] Profitability ratios measure the firm's use of its assets and control of its expenses to generate an acceptable rate of ...
Intuitively, this ratio, referred to as the critical fractile, balances the cost of being understocked (a lost sale worth ()) and the total costs of being either overstocked or understocked (where the cost of being overstocked is the inventory cost, or so total cost is simply ).
Domination analysis of an approximation algorithm is a way to estimate its performance, introduced by Glover and Punnen in 1997. Unlike the classical approximation ratio analysis, which compares the numerical quality of a calculated solution with that of an optimal solution, domination analysis involves examining the rank of the calculated solution in the sorted order of all possible solutions.
Cost-effectiveness analysis (CEA) is a form of economic analysis that compares the relative costs and outcomes (effects) of different courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis , which assigns a monetary value to the measure of effect. [ 1 ]
Two Australian birds have been added to the list of exotic animals South Carolina officials are currently working to track down, following the recent escape of 43 monkeys from a primate research ...
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
