产品功能详情

使用NCSS进行分析

通过一些简单的步骤，您可以获得有意义的数值结果和干净清晰的图形。使用“数据”窗口导入或输入数据。打开NCSS程序进行所需的分析，选择列并运行分析以获得准确且易于阅读的数字输出和图形。

数据管理

NCSS可以轻松导入所有主要类型的数据文件，或者您可以复制和粘贴数据，也可以直接输入数据。NCSS具有出色的过滤和转换功能，可用于管理数据。

程序的选择

 使用下拉菜单，过程搜索或类别树，可以轻松找到正确的分析或图形过程。 可以点击资源查看视频，以了解如何在NCSS中选择所需的过程。

分析设置

分析和图形工具易于使用，并且每个选项都有内置的帮助消息。选择要分析的列，选择所需的报告和图，然后单击“运行”获取结果。如果您需要其他帮助，则只需单击一下即可获得每个过程的完整文档。

地块设计

NCSS提供了80多个地块。一些图是常规分析过程（例如方差分析或回归分析）的一部分，而其他图则是独立工具。所有NCSS地块都是高度可定制的。用户可以控制布局，符号，标题，图例，轴，网格线等。绘图设置易于保存，以备将来使用或共享。

输出流程

运行NCSS程序时，分析结果和所需的图将显示在输出窗口中。可以单击所有图形以在单独的窗口中显示以进行查看或保存。使用输出导航树可以轻松导航输出。 输出和图形已准备就绪，可以查看，复制和粘贴或保存。可以将多个运行结果发送到输出库，以进行保存或比较分析。 

引用NCSS的出版物

总结： Tableau比较适合个人用户以及没有经过可视化分析培训的企业人员使用，使用者能够以最快的时间将自己所掌握的数据以可视化图表的形式展现出来，并通过 Tableau Server 共享给其他用户 ；而Qlik Sense以其丰富的二次开发接口和可扩展性，提供给用户充分的定制能力，使用户可以通过数据加载脚本和 Qlik API 来定制数据连接和可视化报表的展现方式，比较适合较大规模的企业级应用。

NCSS contains a comprehensive collection of statistical procedures for analyzing your data. These procedures cover a wide range of topics, including analysis of variance, clustering, correlation, curve fitting, cross tabulation, descriptive statistics, design of experiments, forecasting, time series, mass appraisal, meta-analysis, mixed models, multivariate analysis, nonparametric tests, operations research (linear programming), proportions, quality control, regression, survival, reliability, comparisons of means, and much more.

Plots, Charts, and Graphs in NCSS

NCSS has a large collection of tools for plots, charts, and graphs. These graphics procedures offer extensive flexibility to get your graph to look just as you want it, while still maintaining ease-of-use and intuitiveness.

NCSS Overview

The home window of NCSS is a column-based spreadsheet where your data can be easily entered or imported from all major statistical or data file types. Straightforward filters, transformations, labels, and formats can be used to get your data exactly as you want it to be.

Then you can choose from over 190 analysis and graphics procedures to analyze and visualize your data.

From a procedure window, you can select the columns you wish to analyze, adjust any other parameters to your liking, and press Run.

Your results will appear in an Output window that is prepared for viewing, printing, copying-and-pasting, or saving. A navigation pane allows you to quickly jump to any part of the output. You can double-click on a graph to save it in any of several file formats.

If you like a particular setup on a procedure window, and would like to perform the same or a similar analysis later, you can save the procedure template to be opened or shared at any time.
