Descriptive statistical analysis is to the data itself, using statistical indicators to describe its characteristics of the analysis method, this description seems simple, in fact, is a lot of advanced analysis of the basic work,
According to the author's press: This article is based on the materials presented at the "Big Data Technology Conference" held by csdn in September, and was originally published in the issue of "programmer" magazine. 1. History R (r development core team, 2011) was developed by Ross ihaka and Robert gentleman at the University of Auckland, New Zealand. Their lexical and syntax are derived from scheme and S languages, respectively, the r language is ge
7 Module Development-statistical analysisNote: Each statistic index can be cross-multiplied with each dimension table, so that the statistical results of each dimension are limited, the code of the cross-multiplication and the comment information are described in the projectEngineering code files, in order to display at the front-end faster, each of the indicators are calculated in advance of the dimensions
Statistical analysis of data is divided into descriptive statistical analysis and statistical inference, the former is also known as exploratory statistical

observation data distribution characteristicSingle-Variable value grouping: Applies to discrete variables with less variable values.Group distance Grouping: Applies to continuous variables with more variable values.Ex: grouping methods and their watchmaking processesStep1: Determines the number of groups. The determination of group number is mainly used for the observation of data characteristics, so it de
the skewness coefficient is greater than 1 or less than 1 , called a highly skewed distribution, if the skewness coefficients are 0.5~1 or -1~0.5 is considered to be a medium-biased distribution; Peak State and its measurement ; the peak state is relative to the standard normal distribution. If a set of data obeys a standard normal distribution, then the value of the peak state coefficient is equal to 0, if the value of the peak state coefficient is
The ability to manage business data during business process management is one of the important functions of the system. This system supports Form Designer design, custom development forms, and custom development reports, by default, the Form Designer provides the data statistics and analysis function for the business data
Distribution When N of the sample distribution is large, the extreme distribution is used as an approximation of the sample distribution. This extreme distribution is called a progressive distribution.Approximate distribution obtained by Random Simulation Distribution of observed values satisfied by repeated experiments.Several Important Distributions derived from normal distribution, Chi-square distribution, tdistribution, and F distribution It plays an important role in variance
central measure of the mean value. A workaround for the mean is the truncated mean, which removes the maximum and minimum number of values and averages the remaining numbers.Memory number Mo median Md mean μ intercept mean TMWhat are the links between these center trend metricsThe answer depends on the degree of bias (skewness) of the dataThe important thing to remember is that we cannot confine ourselves to only one central trend metric. For some data
Presentation This step is simple, reading MySQL data, using highcharts tools such as various displays, you can also use crontab timed PHP script to send daily, weekly, etc.Subsequent updates Recently see some information and other people communicate found that cleaning data this step without PHP, can focus on HQL implementation of cleaning logic, the results are stored in Hadoop, and then use
