statistical data analysis book

11.2 Correspondence AnalysisIn many cases, we are not only concerned with the row or column variables themselves, but the relationship between the row and column variables, which is not explained by the factor analysis method. 1970 French statistician J.p.benzenci proposed correspondence analysis, also called Association analysis, R-Q type factor

Python Data analysisWhy do you choose Python for data analysis?Python will inevitably be close to other open source and commercial domain-specific programming languages/tools such as R, MATLAB, SAS, Stata, etc. for data analysis and interaction, exploratory computing, and

solve multi-class discriminant analysis, but also consider the distribution state of data in analysis, so it is generally more used.X. Principal component AnalysisA set of indicators that palm each other off is transformed into a new set of indicator variables that are independent of each other, and a few new indicator variables can be used to synthesize the mai

associating the model with variables of interest has only recently arisen. Data such as this is usually handled by the generalized estimation equation (general estimating equations, GEE), but the GEE method is progressive and assumes a wide range of samples. I want a generalized linear model with beta-two R. An updated R pack estimates the model: Ben Bolker wrote the Betabinom. and SPSS didn't. Integrated document Publishing. R seamlessly integrates

. Spark+hadoop: Architecture: One of the better technologies in Spark technology is-spark SQL, which enables the use of SQL to manipulate the rdd of Spark, and of course the spark SQL will eventually be used by Spark's engine to be converted into the mapreduce of Spark. Maturity: is still telling development. Efficiency: Overall higher than the hive rate, but if the amount of data is very large, there is no particularl

Recommend several data analysis sitesAs the number of data increases, the data analysis is hot. But many data analysis practitioners do not feel very good access to industry information

scholars have reduced their effects by weighting the statistical parameter graph T contrast of various organizations.Third, the analysis of functional dataAfter preprocessing the data, we use the appropriate algorithm to extract the real representative pixels, that is, the analysis of the function

From the user level of the website, we divide users into different types based on the behavior characteristics of user access, because the user behavior is different, the behavior statistical indicators are different, and the analysis angle is different, therefore, if you want to classify users in detail, you can implement different classifications based on various rules from many perspectives. We have seen

However, products need users, users and products need to be measured, in-depth

Course IntroductionR is a language and operating environment for statistical analysis, mapping, a free, free, open source software for the GNU system, an excellent tool for statistical computing and statistical mapping.The R language grammar is easy to understand and can easily learn and master the grammar of language.

graphs, but the results can be further processed to obtain more detailed results. Each data also has an agent value, that is, the browser's user_agent information, through this information to know the operating system used,so the statistical results generated in the previous step can also be differentiated by operating system differences. Agent value: v. To distinguish a bar chart from an opera

. If you are a company, you need to build a platform for everyone to use. if your work involves statistics, use python. In fact, R can also connect to SQL c ++. The key is to be proficient in one field, and then you will find that everything else is floating cloud ......... Actually, as a heavy user of R and python, I prefer R ...... All of the company's platforms are replaced with python ......... Sorry, I am sorry for the trouble. I want to answer the question and write so much. so I used s
