How can I change height of line break in math mode? I need to add more space between each two lines of the equation.

\begin{gather*}
    EFF_a = \sum_{j=0}^{2} (\frac{ \sum_{i=1}^{4} (EFF_{{a_j}_i} = {\{ p_i; q_i}\}  \rightarrow p_i \cdot q_i)}{ \sum_{i=1}^{4} q_i } \cdot W_{EFF_{a_j})} =
    \\ = \frac{1 \cdot 15 + 2 \cdot 15 + (-1) \cdot 2}{15+15+2} \cdot 0.5 + \frac{1 \cdot 314 + 2 \cdot 101 + (-1) \cdot 33 + (-2) \cdot 4}{314+101+33+4} \cdot 0.4 +
    \\ + \frac{1 \cdot 23 + (-1) \cdot 33 }{23+33} \cdot 0.1 = 1.0743718394437423
\end{gather*}

This produces:

    Or you can add some vertical space manually\begin{gather*} EFF_a = \sum_{j=0}^{2} (\frac{ \sum_{i=1}^{4} (EFF_{{a_j}_i} = {\{ p_i; q_i}\} \rightarrow p_i \cdot q_i)}{ \sum_{i=1}^{4} q_i } \cdot W_{EFF_{a_j})} = \\[2em]= \frac{1 \cdot 15 + 2 \cdot 15 + (-1) \cdot 2}{15+15+2} \cdot 0.5 + \frac{1 \cdot 314 + 2 \cdot 101 + (-1) \cdot 33 + (-2) \cdot 4}{314+101+33+4} \cdot 0.4 + \\[2em] + \frac{1 \cdot 23 + (-1) \cdot 33 }{23+33} \cdot 0.1 = 1.0743718394437423 \end{gather*} – Ice0cean Apr 22 '17 at 12:34
  • @Bobyandbob right, I missed that question. – Arkadiusz Wieczorek Apr 22 '17 at 13:09
  • @Ice0cean thanks, That's what I was looking for. – Arkadiusz Wieczorek Apr 22 '17 at 13:10
