($J \neq 0$) \checkmark \end{itemize} \item Next slide you will know why those assumptions are needed. \end{itemize} \end{frame} \begin{frame}\frametitle{Some mathematical theorems assumptions 3} \begin{itemize} \item Now since there is 1:1 correspondence the central point in the $\overrightarrow{P}$ should be derived from the central point of the $\overrightarrow{S}$ basis. \item Now the confidence belt. In the $\overrightarrow{S}$ a $68\%$ confidence belt ($D$) is: \begin{align*} \int_D f(\overrightarrow{S}) d \overrightarrow{S} = 0.68 \end{align*} \item In this equation our $D$ is effectively the errors that we quote. \item Now form analysis thats to previous slide we can write : \begin{align*} \int_D \underbrace{f(\overrightarrow{S})}_{\rm{What~we~simulate/bootstrap}} d \overrightarrow{S} = \int_{\Delta} \underbrace{f'(\overrightarrow{P})}_{\rm{What~we~get~in~P}} \times \vert J \vert d\overrightarrow{P} \end{align*} \end{itemize} \end{frame} \begin{frame}\frametitle{Toys} \begin{itemize} \item So to get the integral(coverage) correct we need to take the Jacobian into account. \item Let's make a toy example calculating $P_2$. Values used (mean $\pm$ error): $F_l= 0.7679 \pm 0.2$, $A_{FB} = -0.329 \pm 0.13$. \end{itemize} \includegraphics[width=0.85\textwidth]{images/Fl_AFb.png} \end{frame} \begin{frame}\frametitle{Toys} \begin{itemize} \item I am rejecting the non-physical regions: \end{itemize} \includegraphics[width=0.85\textwidth]{images/Fl_boundry.png} \end{frame} \begin{frame}\frametitle{Toys} \begin{itemize} \item Now how does the new space look like. \item Important to take into account the boundary as without all my theorems fall down. \end{itemize} \includegraphics[width=0.85\textwidth]{images/2D.png} \end{frame} \begin{frame}\frametitle{Toys ZOOM} \begin{itemize} \item Now how does the new space look like. \item Important to take into account the boundary as without all my theorems fall down. \end{itemize} \includegraphics[width=0.85\textwidth]{images/2DZ.png} \end{frame} \begin{frame}\frametitle{Toys Conclusions} \begin{itemize} \item One needs to take into account the Jacobian! \item The most probable value agrees perfectly. \item The confidence belt can be transformed analytically even :) \item There is one hack here: one cannot look at $P_2$ stand alone any more: \end{itemize} \begin{columns} \column{2.5in} \includegraphics[width=0.85\textwidth]{images/P2.png} \column{2.5in} \includegraphics[width=0.85\textwidth]{images/cast.png} \end{columns} \end{frame} \end{document}
