Purpose: The purpose of this study is to propose an alternate, quick estimate of standard deviation, represented by s’, and compare its efficiency with the efficiency of other quick estimates of standard deviation, σ. Research Questions: This study questions whether the proposed calculation of s’ is an efficient quick method of estimating standard deviation, and how s’ compares to past quick estimates of standard deviation. Hypothesis: s’ can be used as a quick estimate of standard deviation

aspects needed to achieve the goal and objective of a project. An analogous estimation is a very common estimation technique used to estimate activities within a project through previous experiences with different projects and extrapolates onto the current project at hand. This technique is mainly used for projects that have the same type of work, and the same resources being used between projects. Parametric model estimation is another precise, easy, accurate technique that is used to estimate time

TRUEPLANNING® FOR MORE COMPETITIVE BIDDING ON ADVANCED TECHNOLOGY PROJECTS Challenge: Verify cost estimates to ensure bids are priced to win but are accurate and profitable for each stakeholder in a project’s supply chain. Solution: Create a Cost Estimation Framework (CEF) that uses TruePlanning® top-down, parametric estimating to set cost targets with TrueMapper® feature to cross-check estimators’ bottom-up estimates in Excel based on Work Breakdown Structure (WBS). Improve knowledge capture by creating

From Wikipedia, the free encyclopedia When estimating the cost for a project, product or other item or investment, there is always uncertainty as to the precise content of all items in the estimate, how work will be performed, what work conditions will be like when the project is executed and so on. These uncertainties are risks to the project. Some refer to these risks as "known-unknowns" because the estimator is aware of them, and based on past experience, can even estimate their probable costs

Case Overview Barbara is assigned as the project manager for a competitive bidding job at her company. Typically RFP’s (requests for proposals) at her company are handled by a group of senior managers who will review the RFP and make a decision on whether to proceed. Once the senior managers approve, the proposal department will take over to begin estimating all work along with the help of functional managers, if there is no previous history regarding the deliverables. Generally the project manager

topicmodels: An R Package for Fitting Topic Models Bettina Grun ¨ Johannes Kepler Universit¨t Linz a Kurt Hornik WU Wirtschaftsuniversit¨t Wien a Abstract This article is a (slightly) modified and shortened version of Gr¨n and Hornik (2011), u published in the Journal of Statistical Software. Topic models allow the probabilistic modeling of term frequency occurrences in documents. The fitted model can be used to estimate the similarity between documents as well as between a set of specified

the Internet, cut costs of having a large staff. IT has helped in security management, protecting businesses and clients more than before. Inventory usually estimates demand distribution parameters using historical data. Situations under which a better choice of estimators can reduce the cost because of statistical estimation are closely scrutinized with software for just this (Wagner & Jacobs, 1989). A business can be more accurate with projected expenditures, increasing revenue and decreasing

microstructure noise can cause severe problems in terms of consistent estimation of the daily realized volatility. Independent and dependent noise processes are examined. The most important methods for providing consistent estimators are presented, and a critical exposition of different techniques is given. The finite sample properties are discussed in comparison with their asymptotic properties. A multivariate model is presented to discuss estimation of the realized covariances. Various issues relating to modelling

Rocky Mountain Advanced Genome Case Study 2: Rocky Mountain Advanced Genome This paper provides an objective valuation of Rocky Mountain Advanced Genome (RMAG) to be adopted by Big Sur regarding the purchase of a 90% equity stake for $46 million. Forecast Horizon: The forecast horizon was lengthened to 15 years, as RMAG is a young, “highly promising, high risk” firm, only established 15 months prior, it should reach maturity in 2010 as sales, expenses and free cash flows stabilise (Fig.1)
