Abstract This paper is devoted to the study of asymptotic properties of the regression function kernel estimate in the setting of continuous time stationary and ergodic data. More precisely, considering the Nadaraya–Watson type estimator, say m̂ T ( x ) , of the l -indexed regression function...

The financial theory related to the bond portfolio analysis was coined by Harry Markowitz, an authentic’ pioneer of the modern bond theory’, and his well-thought interpretation of the bond selection model may be found in his research papers “Portfolio Selection” (Markowitz M. Harry,...

The estimation of the regression function, can analyze a transformation of this function. The option for this transformation is grounded by the economic analysis which defines the parameters of interest. A procedure of adjustment is included, consisting of the elimination of the data placed at...

This report comprises an analysis over 40 countries from the group ONECE and over the following two variables : GDP per capita and Unemployment rate in the year 2011. The following report consist of more sections; it begins with calculating the central tendency indicators, which will have a role...

Problems of specification of discrete bivariate statistical models by a modified power series conditional distribution and a regression function are studied. An identifiability result for a wide class of such mixtures with infinite support is obtained. Also the finite support case within a more...

The access to Social and Cohesion Funds offers Romania a possibility to develop the regions which are lagging behind, to modernize transport and environment infrastructure, to support rural development, to create new employment opportunities, to sustain social policies which will lead to the...

Non-parametric methods are useful, but raises some problems. In practice, they require a large number of observations and are used for a relatively small number of explanatory variables. Moreover, the result is sensitive to the choice of the smoothing parameter and to a lesser extent in the...
