Cost estimation in software engineering is typically concerned with the financial spend on the effort to develop and test the software, this can also include requirements review, maintenance, training, managing and buying extra equipment, servers and software. Many methods have been developed for estimating software costs for a given project.
Expert estimation: The quantification step, i.e., the step where the estimate is produced based on judgmental processes. [14] Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data.
These calculations formulate a Basis of Estimate which is, when completed, a number that can be used to determine the ability of the firm or company to carry out the project, or used as a tool in competing for a contract bid or otherwise proposing the project to another.
Cost is the planned cost estimate-to-complete (Cost ETC) of the project. This can usually be derived from earned value management planning by using the complement of the planned value (PV) (i.e., budgeted cost of work performed, or BCWS), which estimates what the sunk cost will be at key reporting points during the project. By subtracting the ...
In statistics, the method of estimating equations is a way of specifying how the parameters of a statistical model should be estimated.This can be thought of as a generalisation of many classical methods—the method of moments, least squares, and maximum likelihood—as well as some recent methods like M-estimators.
