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.Training Courses.

Many courses are part of our prescribed learning tracks and are also offered as public training sessions. Memory based techniques. The items that were already rated by the user before play a relevant role in searching for a neighbor that shares appreciation with him,.Once a neighbor of a user is found, different algorithms can be used to combine the preferences of neighbors to generate recommendations.

Definition. Predictive analytics is an area of statistics that deals with extracting information from data and using it to predict trends and behavior patterns. The enhancement of predictive web analytics calculates statistical probabilities of future events online.

There are few things more complicated in analytics (all analytics, big data and huge data!) than multi-channel attribution modeling. We have fought valiant battles, paid expensive consultants, purchased a crazy amount of software, and achieved an implementation high that is quickly, followed by a.
