Density Estimation by the Modified JACKSON's Method

feasibility of crop density estimation system by optical method

in this study, the possibility of estimating wheat density was investigated by using a non-destructive method of output voltage of the light received by the photovoltaic cells. for the static tests, treatments and procedures, a system was designed and built. an experiment with different density on the wheat crop was carried out. the components of optical system clouding: photocells, led lights ...

The Double Kernel Method in Density Estimation

Let fnh be the Parzen-Rosenblatt kernel estimate of a density f on the real line, based upon a sample of n i.i.d. random variables drawn from f , and with smoothing factor h. Let gnh be another kernel estimate based upon the same data, but with a different kernel. We choose the smoothing factor H so as to minimize ∫ |fnh− gnh|, and study the properties of fnH and gnH . It is shown that the esti...

On Some Two-step Density Estimation Method

We introduce a new two-step kernel density estimation method, based on the EM algorithm and the generalized kernel density estimator. The accuracy obtained is better in particular, in the case of multimodal or skewed densities.

Self-consistent method for density estimation

The estimation of a density profile from experimental data points is a challenging problem, usually tackled by plotting a histogram. Prior assumptions on the nature of the density, from its smoothness to the specification of its form, allow the design of more accurate estimation procedures, such as Maximum Likelihood. Our aim is to construct a procedure that makes no explicit assumptions, but s...
