你可以在RCloud中使用LaTex嗎？

Question

我想寫喜歡用乳膠我的分析，我RCloud筆記本敘事邏輯函數方程（因爲這是我所知道的），例如：

F(x) = 1/(1 + exp(-Ax)) 

g(F(x)) = ln(\frac{F(x)}{1-F(x)}) = Ax 

\frac{F(x)}{1-F(x)} = e^{Ax} 

我可以使用RCloud LaTeX的符號？

Answer 1

是，在一個RCloud的RMarkdown細胞（例如展示在rcloud.social/tryit）筆記本電腦，這將呈現：

### If $x$ is a linear function then the argument to the logistic function can be written as a linear system. 

$$ 
F(x) = 1/(1 + exp(-Ax)) 
$$ 

### $F(x)$ can be interpretted as the probability of the independent variable $x$ producing an output of 1 given the design matrix $A$. 

### When training a binomial logistic regression model we are interested in the inverse problem. That is, given a set of examples what is the optimal value of $A$. 

$$ 
g(F(x)) = ln(\frac{F(x)}{1-F(x)}) = Ax 
$$ 
$$ 
\frac{F(x)}{1-F(x)} = e^{Ax} 
$$ 

### Note that the $g$, called the *logit* function, is equivalent to simple linear regression and 

也是F的數比值（X）。
