Brief introduction IBM SPSS Modeler Entity Analytics (EA) is a new feature added to IBM's SPSS Modeler 15.0 based on the IBM SPSS Modeler 14.2 Predictive analysis. Compared with traditional Modeler, Entity Analytics has a new dimension for data prediction. IBM's SPSS Modeler forecast focuses on predicting future behav

Introduction Data mining software IBM SPSS Modeler is known for its user-friendly, visually powerful features. There are few references to its scripting features. The author believes that the scripting function is actually designed to automate the process of data processing and analysis modeling. In scenarios where data processing needs to be dynamically changed, automatic execution of streams, and automatic execution of batch tasks, some scripts mus

In the actual work, often need to collate the data obtained, so that it meets the specific analysis needs, the following describes the data collation of SPSS some of the functions.1. Weighted caseWeighted cases refer to the different weights given to different cases to change the importance of the case in the analysis. Why did you do it? For example, some of the original data of each row represents a case, in the actual analysis, usually organized int

are subject to a multiclass distribution. When k tends to be infinite, it is almost subject to the overall distribution of X. Therefore, assume that the population is subject to the actual observed frequencies of a certain expected or theoretical distribution set, and obtain the actual observed frequencies of each subset of the sample data. Then, calculate the statistic Q based on the formula below. Where Oi indicates the observed frequency, and Ei indicates the expected or theoretical frequenc

The hypothesis test of statistics can be divided into parameter test and nonparametric test, the parameter test is calculated according to some assumptions, when these assumptions can not be satisfied, the efficiency of the parameter test will be greatly discounted, even the wrong result, and the non-parameter test is usually without the hypothesis condition, so the application scope is wider than the parameter test.Non-parametric testing in the case of no assumptions, the maximum use of sample

analyses have a normal distribution hypothesis, we often also pay attention to the distribution characteristics of the data, common kurtosis coefficients and skewness coefficients to describe the extent of the data deviating from the normal distribution, or you can use the Bootstrap method to calculate the results compared with the results calculated by the classical statistical method, if the difference is obvious Indicates that the original data is biased or has an extremumThe process of

variable diagram is described here, do not make the chart too complicated, otherwise you will lose the chart "intuitive" advantages.To show the correlation of 3 variables, it is best to use three-dimensional coordinates of the three-dimensional statistical chart, but because in fact still on the plane to the three-dimensional diagram, the three-dimensional map is not convenient to use.(1) When a variable is a categorical variable, the two-dimensional graph can be expanded, so that the two-dimen

In SPSS, each variable has a metric that describes the meaning and attributes of the variable and affects subsequent analysis.1. nominal : The nominal class variable, the categorical variable represents the category of things, can only calculate frequency and frequency, there is no size, order, rank between categories. The data for a fixed class variable can be a numeric value, or it can be a character.2. serial number : The sequence number denotes th

: Krumbach a reliability coefficient is the most commonly used reliability coefficient at present. The formula is: a= (k/k-1) * (∑SI2)/st2)Among them, K is the total number of the items in the scale, SI2 is the variance of the problem in the first question, ST2 is the variance of the total score of all the titles. It can be seen from the formula that the evaluation of a coefficient is the consistency between the scores of each item in the scale, which belongs to the intrinsic consistency coeffic

require that there is no correlation between the independent variables, that is, there is no multiple collinearity. However, there is no relevant two variables that are not present, so the conditions are relaxed to be acceptable as long as they are not strongly correlated.Multiple linear regression in the process of SPSS and simple linear regression, just the content of a few more, and because of the more information, it is recommended to set the ana

The first satisfying condition of linear regression is the linear relationship between the dependent variable and the independent variable, and then the fitting method is based on it, but if the dependent variable and the independent variable are nonlinear, then the nonlinear regression is needed to analyze it.There are two processes that can be called in the nonlinear regression of SPSS, one is analysis-regression-curve estimation, the other is analy

Linear regression is most commonly used as a fitting method with least squares, but the method is more susceptible to strong influence points, so when we fit the linear regression model, we also take the strong influence point as the condition to be considered. For strong-impact points, a more robust fit method is needed in cases where it cannot be corrected or deleted, and the least-squares method is the solution to such problems.The least square method is due to the residual sum of squares, an
