Geometrical prediction of maximum power point for photovoltaics

Kumar, Gaurav; Panchal, Ashish K. - In: Applied Energy 119 (2014) C, pp. 237-245

by the Lagrangian interpolation formula, known as the Lagrangian interpolation exploration (LIE). Specifically, this … parallelogram constructed using the open circuit (OC) and the short circuit (SC) points of the I–V characteristic and Lagrangian … interpolation. In the second step, accurate values of voltage and power at the MPP, defined as Vmp and Pmp respectively, are decided …

From the help desk: Polynomial distributed lag models

McDowell, Allen - In: Stata Journal 4 (2004) 2, pp. 180-189

Polynomial distributed lag models (PDLs) are finite-order distributed lag models with the impulse-response function constrained to lie on a polynomial of known degree. You can estimate the parameters of a PDL directly via constrained ordinary least squares, or you can derive a reduced form of...
