Tus WOE yuav tsum yog monotonic i.e. txawm tias loj hlob lossis txo nrog cov bins. Koj tuaj yeem npaj WOE qhov tseem ceeb thiab tshawb xyuas cov kab hauv kab ntawm daim duab.
Vim li cas Woe yuav tsum yog monotonic?
Kev hloov pauv WoE los ntawm monotonic binning muab txoj hauv kev yooj yim los daws txhua qhov kev txhawj xeeb tau hais tseg. … Nws tseem tsim nyog hais tias tus lej sib txawv thiab nws cov haujlwm monotone nruj me ntsis yuav tsum sib koom ua ib qho kev hloov pauv monotonic WoE.
Yuav ua li cas woe siv hauv logistic regression?
Nyhav pov thawj (WOE) coding ntawm nominal los yog discrete sib txawv yog dav siv thaum npaj kev kwv yeesrau kev siv hauv binary logistic regression qauv.
