不等概抽樣,PPS英語短句,例句大全

不等概抽樣,PPS
1)PPS[英][,pi: pi: 'es][美]['pi 'pi '?s]不等概抽樣
1.The NDVI value of sub-compartment pixel could be selected as the auxiliary factor of sampling probability proportional to size (PPS).結果表明:(1)采用小班面積×小班郁閉度(即小班樹冠投影和)作為不等概抽樣(PPS)輔助因子與小班蓄積相關性最好;(2)按齡組與樹種組合分類型優于只按齡組或只按樹種分類型后輔助因子與小班蓄積的相關性;而只按齡組分類型又優于只按樹種分類型后輔助因子與小班蓄積的相關性;(3)小班平均NDVI值×小班面積(即小班像元NDVI值和)與小班蓄積量具有較好的相關性,可以作為小班不等概抽樣的輔助因子,而且較小班面積與小班郁閉度之積有更好的現勢性和可行性。
