拟合优度卡方检验

R语言编程学习，copula函数数据编程分析。相关性分析，R语言的应用(R Copula)

使用R语言进行数据分析的源码，包含数据集(Using R language for data analysis of the source code, including data sets)

水动力模型MIKE21数据后处理 dfsu格式文件导出模拟结果xyz格式文件 R语言可以迅速批量读取xyz文件，并根据文件名排序 以便于后期处理(MIKE 21 export results from dsfu R read numerous xyz files)

说明：  因子分析:包括案例和对应的R语言代码，代码中地址需要自行修改后使用(Factor analysis: including a case and corresponding R language code, the address in the code needs to be modified by itself)

计算CVAR 条件下的最有权重，主要针对股票收益率进行分析(compute the optimal weight under CVAR condition)

结合案例来描述每一种统计学模型，解释如何开展数据分析，讨论采用模拟手段来检验模型，这是模型开发与评估中的重要方面，给出多层回归模型（如多层ANOVA、多层线性回归和广义多层模型），指导如何用R语言采实现诸多方法，在线提供书中所用到的数据集和R语言脚本。(Combined with the case to describe each kind of statistical model, how to carry out data analysis and interpretation, discusses the use of simulation to test the model, this is an important aspect of the development and evaluation of the model, given the multi regression model (such as multilayer ANOVA, multi linear regression and generalized multi model), how to achieve a lot of mining method with the R language guide online provide the data set and the R script used in the book.)

说明：  PSTR模型，解决面板数据的非线性关系问题，适合初学者使用(PSTR model, which solves the problem of non-linear relationship of panel data, is suitable for beginners to use.)

ADS-B接收，采用PlutoSDR板卡，基于matlab开发(ADS-B receives, uses PlutoSDR card, develops based on MATLAB)

主要是利用r语言做简单线性回归，一元线性回归(use r language to solve simple ols)

说明：  R语言舍选法、极坐标法、Box-Muller变换产生正态随机变量(R Language Rounding Method, Polar Coordinate Method and Box-Muller Transform to Generate Normal Random Variables)
