<p>In <a href="page.php?w=probability_theory">probability theory</a>, <b>random element</b> is a generalization of the concept of <a href="page.php?w=random_variable">random variable</a> to more complicated spaces than the simple <a href="page.php?w=real_line">real line</a>. The concept was introduced by  who commented:<blockquote>[the] development of probability theory and expansion of area of its applications have led to necessity to pass from schemes where (random) <a href="page.php?w=Outcome_%28probability%29">outcomes</a> of experiments can be described by number or a finite set of numbers, to schemes where outcomes of experiments represent, for example, <a href="page.php?w=random_vector">vectors</a>, <a href="page.php?w=function_%28mathematics%29">function</a>s, processes, <a href="page.php?w=field_%28mathematics%29">field</a>s, <a href="page.php?w=series_%28mathematics%29">series</a>, <a href="page.php?w=Transformation_%28geometry%29">transformations</a>, and also <a href="page.php?w=Set_%28mathematics%29">sets</a> or collections of sets.</blockquote></p><p>
