Abstract
Weighting or transformations are used for fulfill the assumptions if there is any violation of assumptions in linear regression analysis. Heteroscedasticity is one of the violations these assumptions and butterflydistributed- residuals are particular type of heteroscedastcity. The aim of this study is to examine the effects of transformations variables of regression model for butterfly distributed residuals

Abstract
Klasik doğrusal regresyon analizinde varsayımlar gerçeklenmediğinde, ağırlıklandırma ve dönüşümler kullanılarak varsayım bozulmaları giderilmeye çalışılır. Değişen varyanslılık varsayım bozulmalarından biridir ve kelebek dağılan artıklar da değişen varyanslılığın özel bir halidir. Bu çalışmanın amacı, regresyon eşitliğinde yer alan değişkenlere uygulanan dönüşümlerin kelebek dağılan artıklar için etkilerinin incelenmesidir.
