Just like the topic as follows
${C_p}^\prime (\theta )= \sqrt {\frac{{\sum\limits_{t}{{{\left( {{C_p}(\theta ,t) - {{\bar C}_p}(\theta )} \right)}^2}} }}{{N - 1}}}$ or ${C_p}^\prime (\theta )= \sqrt {\frac{{\sum\limits_{t}{{{\left( {{C_p}(\theta ,t) - {{\bar C}_p}(\theta )} \right)}^2}} }}{{N }}}$ Which item will you choose? Thanks |
