Bonjour ,
J'ai un problème avec LaTeX
Code:\begin{align*} \hspace{-2cm} E\{(1-R_{t})R_{0t}\} &\geq E[\{I(y_{t-d}>r_{U})+I(r_{U}\geq y_{t-d}>r_{L}) I(y_{t-d_{0}-1}>r_{U})\} \times \{I(y_{t-d_{0}}\leqslant r_{0L}) + I(r_{0L}<y_{t-d_{0}}\leqslant r_{0U})I (y_{t-d_{0}-1}\leqslant r_{0L})\}] \\ &\geq pr(y_{t-d_{0}}\leqslant r_{0L} ,y_{t-d}>r_{U} ) + pr(y_{t-d_{0}}\leqslant r_{0L},r_{0U}\geq y_{t-d}>r_{U}, y_{t-d-1}>r_{U} ) \\ +pr(r_{0L}< y_{t-d_{0}} \leqslant r_{0U},y_{t-d_{0}-1}\leqslant r_{0L} , y_{t-d}>r_{U}) \end{align*}
