In this article we have adapted productivity analysis to the case of a cost model using a quadratic cost function and discrete data. The main theoretical result is a productivity index that can be ...

Often neither the exact density nor the exact cumulative distribution function (c.d.f.) of a statistic of interest is available in the statistics and econometrics literature (e.g., the maximum ...

Abstract: In this article, an unified distributed multiagent system is proposed to minimize the time-varying quadratic function under the time-varying coupled equality constraint, which is further ...

Polynomials and power functions are the foundation for modelling non-linear relationships. Polynomial functions such as quadratic, cubic and quartic model variables raised to exponents of different ...

Abstract: This paper describes a novel method to mid-long term runoff prediction using moving windows autoregressive quadratic model which combines autoregressive quadratic model and moving windows ...
