摘要
This paper introduces the mixture of left-right truncated normal distributions, from the spreads between bid and ask prices, as a statistical model for handle non-normality of asset price returns. It has been proved that there is only one maximum for the likelihood function of the new model. (C) 2009 Elsevier B.V. All rights reserved.
