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

+i+e, V represents the effective fraction, I represents the system error fraction, and the validity of the error is further decomposed into the system error, but the true fraction is also renamed as the effective fraction.Reliability can be expressed by the reliability coefficient, different analysis purposes have different reliability coefficients, according to the focus of attention is different, can be divided into internal reliability and external

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 Modele

Previously, we captured and processed Weibo data in a simple way. This article analyzes the similarity of sch

: 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

The T-Test in SPSS is all concentrated in the analysis-compare mean menu. About the T-Test again, we know that a statistical result needs to be expressed in three parts: concentration, variability, and significance.The centralized performance indicator is the mean valueVariance, standard deviation, or standard error is the performance indicatorThe significance is to determine whether to achieve the signific

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

decomposed into 3 parts: the sum of squares caused by the individual action of multiple control variables; the sum of squared deviations caused by the interaction of multiple control variables; the sum of squared deviations caused by other stochastic factors3. Covariance analysis: It is difficult to control the factors as a co-variable, in the context of the influence of the dispatch of the covariance, analysis
