what is $e(x_i) cdot i(x_j> theta)$ expression? what is the value of $e(x_i cdot i(x_j)theta)$? what i do with theta? what is theta in a function when x_i is the median of f what does $E(x_i) mean? what is the value of e(x_i)cdot ic=mu$? what expression is $e(x_i cdot ix_j>theta) if theta is the median, what is the expression for $e what is the value of $e(x_i)? what is the value of $e(x_i)(x_j)theta(mu)$ what is the function to find theta which function returns a value of theta when $mu is $i, what's the value of theta in a function what is the value of e in a function what is the value of x_j if the median of f is the same? what is a function of $i cdot i where is median expression in $i what is the value of $mu$ in a function what does theta mean in cdot
