  • Sensitivity Analysis

    1237 Words  | 3 Pages

    Sensitivity Analysis A technique used to determine how different values of an independent variable will impact a particular dependent variable under a given set of assumptions. This technique is used within specific boundaries that will depend on one or more input variables, such as the effect that changes in interest rates will have on a bond's price. Sensitivity analysis is a way to predict the outcome of a decision if a situation turns out to be different compared to the key prediction(s).

  • The ID3 Algorithm

    1344 Words  | 3 Pages

    The ID3 Algorithm Abstract This paper details the ID3 classification algorithm. Very simply, ID3 builds a decision tree from a fixed set of examples. The resulting tree is used to classify future samples. The example has several attributes and belongs to a class (like yes or no). The leaf nodes of the decision tree contain the class name whereas a non-leaf node is a decision node. The decision node is an attribute test with each branch (to another decision tree) being a possible value of

  • Liberalism, Distributive Subjectivism, and Equal Opportunity for Welfare by Richard Arneson

    1996 Words  | 4 Pages

    The desire theory of wellbeing, or preference-satisfaction, traditionally argues that desire-satisfaction adequately measures overall subjective wellbeing. Yet in his article ‘Liberalism, Distributive Subjectivism, and Equal Opportunity for Welfare’ (1990), Richard Arneson alludes to challenges with preference-satisfaction in the analytic discourse, and establishes his own conception of subjective wellbeing. My aim in this essay is to evaluate Arneson's account of hypothetical ideally considered

    number of factors, the main ones being: · the size of the settlement in terms of its population · the range and number of services a settlement has · the sphere of influence or the size of the area served by the settlement. The best way to show the urban hierarchy is by using a pyramid, as shown in this diagram. [IMAGE] The most obvious way of deciding where a settlement ranks on the urban hierarchy is by using the population of that settlement. The larger the population, the

  • Why Is Monopolies Harmful And How Can Regulation Ameliorate These Harm

    859 Words  | 2 Pages

    There are several reasons why monopolies may be against the public interest. It is claimed that monopolies produce at a lower level output and charge a higher price than under perfect competition in both the short run and the long run. Consider the diagram above. Assume that this monopolist attempts to maximise profits. Equating MC=MR yields an output of Qm and a price of Pm. If the same industry existed under perfect competition however, the price would be Ppc and output would be Qpc since under perfect

  • Costs, Profits and Break-even Analysis

    5441 Words  | 11 Pages

    Costs, Profits and Break-even Analysis Alas, this means coming to terms with numbers, something that seems to frighten a large proportion of Business Studies students. Before reaching the stage of actually drawing a break-even diagram we need to think what actually goes into one. First, we need to look at costs. They can be referred to in terms of output, time or product. When we speak of costs in terms of output and time we mean FIXED and VARIABLE costs. Remember fixed costs do not vary

    census. Each punch card contained the data of each individual. Operators fed the countless cards into the computer. When the spring-mounted nails of the computer passed through the holes of the punch-card, an electric circuit was completed. As seen in diagram C, the results of each card were displayed on rows of dials. Hollerith’s company, the Tabulating Machine Company, was eventually sold and was renamed the International Business Machines Corporation (IBM) in 1911, which still exists today. The first

  • Productivity In Construction Industry

    679 Words  | 2 Pages

    1.1 General Construction labour productivity has become big problem in construction industry. In many countries, labour cost comprises 30 to 50% of the overall project’s cost (Yates and Guhathakurta, 1993), and thus is regarded as a true reflection of the economic success. Because construction is labour-intensive industry, significance of this effect not only justifies the concern over its labour productivity, but it can also be argued that labour power is the only productive resource. There are
