In the classical probability in continuous random variables there is no distinguishing
between the probability involving strict inequality and non strict inequality. Moreover a …

In this paper we propose a new procedure for testing independence of random variables,
which is based on the conditional expectation. As it is well known, the behaviour of the …

In this paper, we present alternative methods to evaluate the presence of the arbitrage
opportunities in the market. In particular, we investigate empirically the well-known put-call …

In this paper we are interested in approximating the conditional expectation of a given
random variable X with respect to the standard normal distribution N (0, 1). Actually we have …

This paper proposes an alternative method to evaluate the independence between random
variables. The new method is particularly useful when the tested random variables are …
