Hello, I am m.s of systems engineering and b.s of industrial engineering and I have passed many related courses such as mathematics, probability, statistics that statistics is the base of my major, hypothesis testing, confidence interval (that I made a spreadsheet for it too), analysis of variance, regression (that I passed also econometric that is advanced regression), I have good command of English too). I have lots of experience with softwares such as SPSS, SAS, excel and worked on regression, to be honest after seeing your bid I searched about decomposition in regression and found it very interesting and I will be happy if I know more so I can work with you on this.
