koolreport/statistics

Composer 安装命令:

composer require koolreport/statistics

包简介

Provide various statistical measures for data

README 文档

README

Talking about data, we also talk about statistics because we learn about data through statistics. The Statistics package allows you to compute basic and advanced statistical measures for columns of your data. The basic measures could be min, max, mean, median, etc. The advanced measures are, for example, lowerQuartile, popStdDeviation and others.

Installation

By downloading .zip file

  1. Download
  2. Unzip the zip file
  3. Copy the folder statistics into koolreport folder so that look like below
koolreport
├── core
├── statistics

By composer

composer require koolreport/statistics

Documentation

Quick start

In your report's setup page, use the process \koolreport\statistics\Statistics with an array parameter in the type of '{{statistical measure}}' => '{{array of column names}}'

<?php
//MyReport.php
use \koolreport\statistics\Statistics;

class MyReport extends \koolreport\KoolReport
{
    ...
    function setup()
    {
        $this->src('sales')
        ->pipe(new Statistics(array(
            'min' => array('2003'),
            'max' => array('2003'),
            'mean' => array('2003', '2004'),
            'median' => array('2003', '2004', '{{all}}'),
            'lowerQuartile' => array('2005'),
            'upperQuartile' => array('2005'),
            'meanDeviation' => array('{{all}}'),
            'stdDeviation' => array('{{all}}'),
            'percentile_10' => array('{{all}}'),
            'percentile_90' => array('{{all}}'),
        )))
        ->pipe($this->dataStore('salesYearMonthStatistics'));
    }
}

Then in your view, you could use the utility StatisticsReader to extract the measures:

<?php
    //MyReport.view.php:
    use \koolreport\statistics\StatisticsReader;
    
    $stats = StatisticsReader::read($this->dataStore('salesYearMonthStatistics'));

    echo $stats['min']['2003'];
    echo $stats['median']['2004'];
    echo $stats['percentile_90']['{{all}}'];
?>

Properties

The package supports the following statistical measures:

name description
min Returns the first minimum value of a data series.
max Returns the first maximum value of a data series.
mode Returns the first most common value of a data series.
mean Returns the average value of a data series.
median Returns the middle value that divides a data series into 2 equal halves when ordering.
lowerQuartile Returns the first quartile of the quartiles that divides a data series into 4 equal group when ordering. The second quartile is the median.
upperQuartile Returns the third quartile.
percentile_X Returns the value that X percentage of a data series fall below when ordering. X is an integer from 0 to 100.
meanDeviation Returns the mean absolute deviation value of a data series in the formula of Sum of absolute(elementValue - mean) / length of data series.
popStdDeviation Returns the population standard deviation value of a data series in the formula of Square root of (sum of square(elementValue - mean) / length of data series).
samStdDeviation Returns the sample standard deviation value of a data series in the formula of Square root of (sum of square(elementValue - mean) / (length of data series - 1)).

koolreport/statistics 适用场景与选型建议

koolreport/statistics 是一款 基于 PHP 开发的 Composer 扩展包,目前已累计 182.65k 次下载、GitHub Stars 达 3, 最近一次更新时间为 2019 年 05 月 09 日, 在 PHP 生态内属于活跃度较高的组件。

它主要适用于以下技术方向: 「php」 「statistics」 「min」 「mode」 「mean」 「max」 等业务场景。在实际项目中,围绕这些方向常见需要落地的问题包括:接口对接、性能调优、并发安全、与既有框架(Laravel / ThinkPHP / Yii / Webman 等)的兼容适配,以及生产环境的日志埋点与稳定性保障。

我们在过去多个企业项目中使用过 koolreport/statistics 或与其功能相近的方案,如果你在选型或落地过程中遇到问题,例如 版本兼容、二次改造、私有化封装、与内部系统对接、生产 BUG 排查,欢迎联系我们协助评估。
