predictive models for data mining:
Predictive data mining, which produces the model of the system described by the given data set.
some of the different types of predictive models are:
Each of these types has a particular use and answers a specific question or uses a certain type of dataset. Despite the methodological and mathematical differences among the model types, the overall goal of each is similar: to predict future or unknown outcomes based on data about past outcomes.
Smart Predict is currently able to train predictive models that deal with classification, regression, and time-series forecasting scenarios. The scenario you choose depends on the business question you’re trying to answer.
Classification Scenario
If you’re trying to determine the likelihood of whether or not
something will happen, you’re dealing with a classification
scenario.
For example, if your question is whether or not your customers will respond to a marketing offer, you can use a classification scenario to determine the probability of response for each of your prospective customers. This allows you to focus your efforts on targeting customers who are most likely to buy.
Regression Scenario
If you’re trying to predict a numerical value and explore the key
drivers behind it you’re dealing with a regression scenario.
For example, if you want to predict the employee employment duration you would use a Smart Predict regression scenario. This will identify relationships in your data to help you better understand what factors lead to long-term employment. The result? These valuable insights can be used to influence your HR policies and reduce employee attrition.
Time Series Scenario
If you’re trying to forecast a future numerical value based on
fluctuations over time, seasons, and other internal and external
variables, you’re dealing with a time series scenario.
For example, a time-series predictive model can predict future sales volumes by analyzing historical sales data over time. This sales data, combined with additional information about your current sales force, marketing activities, or environmental factors like weather, can be used to project future performance trends.

We have three candidate predictive models shown below automatically generated to solve the regression task of predicting variable y given a another variable x. All three models are approximations of the underlying function given only the provided training data. Recall that supervised data mining is difficult due to the issue of picking one of the infinite number of potential predictive models. The true underlying relationship is denoted by the green function Predictive Model 1 Predictive Model 2 Predictrve Model 3...
Which of the four types of analysis could be used by logistical regression and why? (predictive,descriptive,diagnostic,prescriptive)
Data are used in business to develop solutions and drive business results in different ways. Describe how your business or industry uses descriptive, predictive, and prescriptive analytics as part of the business. In replies to peers, provide analysis and additional alternatives to types of data used in analytics.
Identify the statistical tests used to analyze the data in the study. Are there other statistical analysis methods that would have been more appropriate? If so, identify them and discuss. Describe the limitations of the study. Identify and describe any factors that may have affected the results of the study. Can the results of the study be applied, and if so, to whom? How could results of the study impact healthcare practices? Explain and discuss. Hansen, L. O., Williams, M....
Discuss examples in which statistical methods are used, or have been used, in chemical analysis. Identify the statistical methods used, and describe the implementation of these methods as well as the benefits obtained from their use. Explain using f-Test, t-Test, Grub's test, methods in least-squares/linear regression analysis, and multivariate analysis (ANOVA). Do not use methods in principle components analysis (PCA), PCR, Simplex optimization.
Descriptive statistics like mean, median, range, and standard deviation can be used to summarize data. But the value isn't in knowing how to calculate these numbers, it's in knowing what they mean—or even which ones to consider. This discussion explores that by asking you to take a strictly hypothetical look at a serious circumstance. An article you might want to consider in this context is Stephan Jay Gould’s The Median Isn’t the Message. 1. If you were diagnosed with a...
1) Assuming that data mining approaches are to be used in the following cases, identify whether the task required is supervised or unsupervised learning: a. A service that has a large number of people repeatedly label photos as to whether or not they contain an object of interest, then wants to use that data to label new photos. b. A photo-sorting app that takes all your photos of people and automatically divides them into different groups, each group ideally containing...

EA8-C1 Discuss Worksheet Protection Protection can be used at multiple levels to protect workbooks, worksheets, and individual cells. In the case of the bond amortization schedule, this protection ensures that users adjust only certain cells and cannot inadvertently alter elements that should remain static. However, a bond amortization schedule is not the only worksheet for which protection is appropriate. Depending on factors such as the frequency with which a worksheet is disseminated and the number of users with access to...
