Another DataFrame Dataset A dataset or data set is a collection of data. A dataset is organized into some type of data structure. In a database, for example, a dataset might contain a collection of business data names, salaries, contact information, sales figures, and so forth. These include the number and types of the attributes or variables, and various statistical measures applicable to them, such as standard deviation and kurtosis.
The reason why the father wished to close down the branch was that it appeared to be making a loss. However, it is quite the reverse; if the branch was closed then, the positive contribution from the branch would be lost and overall profits would fall.
This is because the indirect costs of production do not vary with output and, therefore, closure of a section of the firm would not lead to immediate savings. This may mean that closing the branch would be a mistake on financial grounds.
This mistake is made due to a misunderstanding of nature of cost behavior. If the branch is closed then the only costs that would be saved are the costs directly related to the running of the branch: The costs are indirect in nature, in this example the marketing and central administration costs, would still have to be paid as they are unaffected by output.
For this decision to be made, we should use contribution as a guide for deciding whether or not to close a branch.
This can also be applied to the production of certain product lines, or the cost effectiveness of departments. On financial grounds, contribution is therefore, a better guide in making decisions.Systems Simulation: The Shortest Route to Applications.

Jan 01, · Evolutionary polynomial regression The EPR is a data-driven technique based on the evolutionary computation (Giustolisi and Savic, ), which deals with pseudo-polynomial structures representing a true physical system. Box and Cox () developed the transformation. Estimation of any Box-Cox parameters is by maximum likelihood.
Box and Cox () offered an example in which the data had the form of survival times but the underlying biological structure was of hazard rates, and the transformation identified this. In this thesis a new evolutionary polynomial regression (EPR) based approach is presented for constitutive modelling of soils.
EPR is an evolutionary computing method that.
