A Researcher from Kerbala University Presents a Scientific Research for Using regression analysis as a method for costing estimate and decision making

A lecturer from Collage of Administration and Economics /Kerbala University has published a scientific study for Iraqi Journal For Administrative Sciences, Iraq, Volume 5 – Issue 21 – 2008
Dr. mohammed wafi Abd Eawn

The  accountant  is  distinguish  between  fixed  costs  and  variable  costs  through  checking  of  ledger  accounts  and  its  classification  into  three  groups : fixed  costs , variable  costs , and  mixed  costs . then  separate  of  mixed  costs  and  determine  the  ratio  of  variable  costs  and  ratio  of  fixed  costs  in  the  total  of  mixed  costs  in  order  to  be  taken  into  account  in  estimation  of  future  costs . this  process  is  perform  on  basis  of  experience  and  personal  diligence , then  loss  of  large  amount  of  objectivity  and  that  is  trace  wrong  decisions .

       This  research  aims  to  preparation  of  cost  equation  to  research  sample  company  with  regression  analysis  style  and  knowledge  of  its  effect  on  decisions  marking .

      This  research  depends  on  the  following  hypothesis :-   

(( taking  the  regression  analysis  model  in  preparation  of  cost  equation  will  ensure  correct  separation  between  fixed  costs  and  variable  costs  and  estimation  of  future  costs , and  then  providing  relevant  information  to  the users  in  order  to  true  decisions  making ))

       This  research  is  divided  into  paragraphs  deals  with  the  research  methodology , theoretical  presentation  to  this  model , hypothesises , and  tests , then  an  applicative  part  which  included  determine  the  depended  variable  and  independed  variable , then  implementing  the  model  and  its  evaluation  process , also  include  model  effect  on  decisions  making , then  showing  the  important  conclusions  that  revealed  by  the  study  and  giving  the  suggested  recommendations .
