Nonlinearity in the relationship between mutual funds and market returns is often assumed when market timing is assessed. Hence, a quadratic term is introduced into the classic linear model to measure market timing. However, nonlinearity could be due to other factors and the evidence of market...

Tracking the correct directions of monotonicity in multi-dimensional modeling plays an important role in interpreting functional associations. In the presence of multiple predictors, we provide empirical evidence that the observed monotone directions via parametric, nonparametric or...

Static tax-benefit microsimulation models (MSM) are widely used and reputed tools for public policy analysis but a more than careful use of them is compelling. This paper focuses on the analysis of MSM output, suggesting to use nonparametric kernel methods rather than most often used histograms...
