I am now to the Beijing University of Sociology statistics, in addition to SPSS there is no software available, the domestic this is very poor. I will now use FORTRAN, compi

analysis.Factor analysis is a multivariate statistical method that transforms several measured variables into a few unrelated comprehensive indexes. In practical application, it is an effective method to reduce the variables. As we all know, the cognition of things is often multi-dimensional, such as Chinese input method software, will be in the input speed, accuracy, easy to learn, easy to operate, interface-friendly and so on five different cognitive evaluation. and choose which kind of input

process, is the difference between the two mean (mean) the significance of the test. The T-Test must know whether the variance of the two populations (variances) is equal, and the calculation of the T test value will vary depending on whether the variance is equal. In other words, the T test depends on the variance homogeneity (equality of variances) results. Therefore, SPSS in the t-test for equality of means, but also to do Levene ' s test for equa

In recent months has been in a very busy state, every day like a headless flies, East study, Western learning, although learning a lot of things, but most of them are shallow, not deep enough. This essay, half in order to vent their emotions, half in order to set goals for the next few months of study. Statistical basis: Summarize the various statistical methods. Parameter estimation, nonparametric estimation, hypothesis test, variance analysis, chi-square test, correlation analysis, linea

Brother Wen talked about your use of the S language, do not know whether it is useful. Reference books also do not know how to find out. No matter what, trouble brother find a copy to me, just forget it. As far as I can see, it's enough to solve a variety of matrix operations: Of course, there are various dist

consumption amount, a certain competitive strategy should be launched to win these customers from their competitors. Line M: indicates the amount of the customer's consumption each time. You can use the last consumption amount or the previous average consumption amount. Different identification methods can be used based on the analysis purpose. Generally, a customer with a large transaction amount has a strong payment ability and low price sensitivity. This is a relatively high-quality customer

Proc export can export two types of files: Export the delimited file1 * example; 2 proc export data = hotels 3 OUTFILE = 'C: \ myrawdata \ Alibaba s.txt '/* The suffix name determines the format of the output file. In addition, the value can also be specified using the DBMS = option. */4/* For example, if the space-delimited file does not have a standard suffix, you can only use the DBMS = option to output */5 DBMS = DLM/* If the CSV file is output, DBMS = CSV; 6. If the TXT file is output, DB

CT was used for low-dose chest scan with 6th groups of 110kv. Statistical analysis: SPSS 10.0 software was used for relevant statistical analysis to detect the comparison of multiple groups of absorbed dose using the single-factor variance analysis method. The overall comparison adopted the Welch approximate variance analysis, and the Levene statistics were calculated, the differences between two groups were statistically significant. LSD or tamhane'

quantitative approach to help us make the final decision. Look at a set of data for thisCan we use this set of data to build multivariate linear regression models? Again, to plot the scatter plot as follows, the argument seems to be a bit collinearity, but not as obvious as the example above, what to do now?So we're suggesting a more quantifiable approach to describing the seriousness of the problem, rather than just making perceptual decisions by looking at it visually. Below I demonstrate the
