of technical analysis. Nonetheless‚ people’s curiosity about past data has never gone. Being different from the vast majority who use typical technical analysis‚ we decide to use predictive data mining techniques which we regard as interesting and accurate in our forecasting. Forecasting is an uncertain process and therefore a high accuracy is demanded. There are many forecasting techniques in the world. In general‚ they can be classified into three types: casual model‚ time-series model and smoothing

make as accurate as possible forecast. A right combination of quantitative and qualitative methods is to be used. * Qualitative Techniques Qualitative techniques are generally used when there is insufficient data available for quantitative analysis. They are also known as subjective methods as they are dependent upon intuition based on experience‚ intelligence‚ and judgment. They are also preferred for giving a quick estimate and cost savings. Some of these techniques are as follows –

for improvement. Mr. Williams was approached by his Director of Marketing‚ Mr. Barney Thompson‚ and announced that they had lost a large order due to a backorder of tubing‚ which is used during their manufacturing process. This was not the first time that that Mr. Williams has heard bad news like this recently.

keeps cost low‚ is outsourcing most of its products from material and assembly plants located in the Pacific rim (while being in North America) worth waiting the two to three months for it to ship? Perhaps C&F should look into the cost-benefit analysis of outsourcing so far away and looking at more domestic sources‚ such as what Zara has that supplies them in typically two to three weeks. If C&F weren’t outsourcing as much‚ they could get their products in faster‚ and thus getting to customers

paper‚ multivariate time series models were built to predict the power ramp rates of a wind farm. The power changes were predicted at 10 min intervals. Multivariate time series models were built with data-mining algorithms. Five different data-mining algorithms were tested using data collected at a wind farm. The support vector machine regression algorithm performed best out of the five algorithms studied in this research. It provided predictions of the power ramp rate for a time horizon of 10–60 min

find different kinds of patterns. There are two classes of data mining taxonomy which are predictive and descriptive (Akkaya & Uzar‚ 2011). The data mining tasks that are most apply‚ use and popular are classification‚ association‚ clustering‚ trend analysis and regression (Fu‚ 1997; Gheware et al.‚ 2014). • Classification is the derivation of a function or model which determines the class of an object based on its attributes. A set of objects is given as the training set in which every object is represented

income changes. Thus‚ permanent income changes are mostly consumed while temporary income changes are mostly saved. For example‚ if you get promoted and you get a salary increase‚ this change will be probably permanent and so your consumption over time will probably rise. If instead you win the lottery‚ this represents a transitory income and you will probably not consume all of this transitory income. The key point is that the consumption plan does not depend on the transitory components. To
