The subroutines glkern.f and lokern.f use an efficient and fast algorithm for
automatically adaptive nonparametric regression estimation with a kernel method.
Roughly speaking, the method performs a local averaging of the observations when
estimating the regression function. Analogously, one can estimate derivatives of
small order of the regression function.
C G I又稱通用網(wǎng)關(guān)接口(Common Gateway Interface)，是外部程序和We b服務(wù)器之間的標(biāo)
準(zhǔn)編程接口， P H P隱藏了其中的大部分復(fù)雜性，但是，了解一些它的基本內(nèi)容對設(shè)計(jì)應(yīng)用程
序和進(jìn)行調(diào)試都有很大幫助。
