This paper puts forward an alternative approach to multiplicative models and their assessment of returns out of financial assets. Firstly, it lays down an operative definition but also sets forth a commutative framework of mappings to provide foundations to such a definition. Next, the total...

Purpose This paper aims to develop a methodology to accurately and timely measure movements in housing markets by constructing a continuously estimated house price index. Design/methodology/approach The continuous index, which is extracted from an additive model that includes the temporal and...

P(enalized)-splines and fractional polynomials (FPs) have emerged as powerful smoothing techniques with increasing popularity in several fields of applied research. Both approaches provide considerable flexibility, but only limited comparative evaluations of the performance and properties of the...
