将plm模型概括为r中的方程 [英] Summarize plm model as an equation in r

问题描述

在我的论文中，我估计了不同的内。和汇集使用plm软件包的plm（）建立模型。另外，我通过使用时滞修改了一些模型。所有模型都运行良好，我得到了结果。现在，我想通过显示模型方程来可视化模型。所以我的问题是：

有没有一种方法可以从模型中提取方程式？

在之前，我会以最基本的方式使用它任何计算都可以完成。...
或多或少像这样，因为

对于我的模型，我使用面板数据集，而我的模型看起来更像这样（只是更多的控制变量）。

p>

model1<-plm（a〜b + c，模型=内部，数据）

谢谢

解决方案

首先，请尝试使用数据框示例制作可复制的示例，如果您使用外部软件包时，请务必注明。参见 https://stackoverflow.com/help/how-to-ask 。

第二，假设它是软件包 plm 中的函数，则对象 model1 应该具有系数。

等式如下：

  model1 $ coefficients [1] + model1 $ coefficients [2] * b + model1 $ coefficients [3] * c + model1 $ coefficients [4] * d 
  

此外，由于您要声明数据，因此可以将调用简化为：

  model1<-plm（a〜b + c + d，model = within，data）
  

In my thesis i estimated different "within" and "pooling" models using plm() of the plm package. Additionally, i modified some models by using a time lag. All the models work well and i got my results. Now i would like to visualize the models by showing their equation. So my question is:

Is there a way to extract the equation from the model?

I would need it in the most basic way, before any calculation is done.... more or less like this because it is not about showing my results, but the math i use.

For my models i use a panel dataset and my models look more less like this (just more control variables).

model1 <- plm (a ~ b + c, model = "within", data)

Thank you

解决方案

First, please try to make a reproducible example with a sample of your dataframe, and if you are using an external package make sure to state it. See https://stackoverflow.com/help/how-to-ask.

Second, assuming it's the function from package plm as it seems, your object model1 should have the coefficients.

The equation would be something like:

model1$coefficients[1] + model1$coefficients[2] * b + model1$coefficients[3] * c + model1$coefficients[4] * d 

Also, since you are stating the data, you could simplify your call as:

model1 <- plm (a ~ b + c + d, model = "within", data)
