在 R 中绘制数据集的 CDF？
我不太确定 CDF（累积分布函数）和 ECDF（经验累积分布函数）之间的区别，但我通常使用 CDF 图来观察我的数据。
我最近一直在使用 R，并且拼命地想找出如何绘制我的数据的 CDF 和 CCDF（互补 CDF）。我所能找到的只是 R 有 ecdf 但我不确定这是否是我正在寻找的。绘制 ECDF 非常简单：
plot.ecdf(data)
有谁知道如何使用 R 绘制数据集的 CDF 和 CCDF？
I am not really sure about the difference between CDF (Cumulative Distribution Function) and ECDF (Empirical Cumulative Distribution Function) but I usually utilize a CDF plot to make observations about my data.
I have been using R recently and am desperately trying to find out how to plot a CDF and CCDF (Complementary CDF) of my data. All I could find was that R has ecdf but am not really sure if this is what I am looking for. Plotting an ECDF is as simple as:
plot.ecdf(data)
Does anyone know how to plot a CDF and CCDF of a dataset using R?

当您知道或假设分布时，CDF 通常需要封闭形式。另一方面，ECDF 是“经验性的”，因为它来自您的数据。我刚刚回答了有关使用
ecdf()和 Hmisc 的Ecdf()在这里 前几天。更一般地说，您可以使用术语在此处进行搜索，例如
在搜索框中查找 R 标签内的“ecdf”。在 rseek.org 上，几乎没有出现“ccdf”的情况。这可能与减去 ECDF 相同吗？如果是这样，Hmisc 中的
Ecdf()就可以做到。我希望这会有所帮助，如果没有，请重新表述您的问题，因为尚不清楚您到底在寻找什么。
ecdf()和Ecdf()都非常有功能，因此请务必阅读它们的帮助页面。A CDF commonly requires closed form when you know or assume a distribution. An ECDF, on the other hand, is 'empiricial' as it comes from your data. I just answered a question about using
ecdf()and Hmisc'sEcdf()here the other day.More generally, you can search here using terms such as
in the search box to look for 'ecdf' within the R tag. At rseek.org, little comes up for 'ccdf'. Is that maybe just the same as one minus the ECDF? If so,
Ecdf()in Hmisc can do it.I hope this helps, if not please re-phrase your question as it is not quite clear exactly what you are looking for. Both
ecdf()andEcdf()are pretty featureful so make sure to read their help pages.
