Kernel Smoother

A kernel smoother is a statistical technique for estimating a real valued function by using its noisy observations, when no parametric model for this function is known. The estimated function is smooth, and the level of smoothness is set by a single parameter.

This technique is most appropriate for low dimensional (p < 3) data visualization purposes. Actually, the kernel smoother represents the set of irregular data points as a smooth line or surface.

Famous quotes containing the words kernel and/or smoother:

    All true histories contain instruction; though, in some, the treasure may be hard to find, and when found, so trivial in quantity that the dry, shrivelled kernel scarcely compensates for the trouble of cracking the nut.
    Anne Brontë (1820–1849)

    The words of his mouth were smoother than butter, but war was in his heart: his words were softer than oil, yet were they drawn swords.
    Cast thy burden upon the Lord, and he shall sustain thee: he shall never suffer the righteous to be moved.
    Bible: Hebrew Psalm LV (l. LV, 21–22)
