在方程式中将 LaTeX 分数项排版更大 [英] Typesetting LaTeX fraction terms to be larger in an equation
问题描述
我在 LaTeX 中有以下公式,基于
(来源:
I have the following formula in LaTeX, based on Fisher's Exact Test. (NOTE: requires the use of the amsmath
package for inom
.)
egin{equation}
P(i,j) = sum_{x=|N(V_i) cap V_j|}^{min{|V_j|, |N(V_i)|}
frac{ inom{|V_j|}{x} inom{|V - V_j|}{|N(V_i)| - x}}
{inom{|V|}{|N(V_i)|}}
end{equation}
This renders the fraction portion with very small, difficult to read text:
I would like my text more readable, as in the following example:

What trickery can I use to get LaTeX to render my equation similarly?
This may be what you're looking for:
egin{equation}
P(i,j) = sum_{x=|N(V_i) cap V_j|}^{min{|V_j|, |N(V_i)|}
frac{displaystyle inom{|V_j|}{x} inom{|V - V_j|}{|N(V_i)| - x}}
{displaystyle inom{|V|}{|N(V_i)|}}
end{equation}
Thought it might be good to add a reference:
