Temel Bilesenler Analizi olan PCA tanima, siniflandirma, goruntu sikistirma alanlarinda kullanilan yararlı bir istatistiksel tekniktir. Temel amaci cok sayida birbiri ile iliskili degiskenler iceren veri setinin boyutlarini veri icerisinde var olan degisimlerin mumkun oldugunca korunarak daha az boyuta indirgenmesini saglayan bir donusum teknigidir. Eldeki veriyi daha az sayida degiskenle ifade edebilecek en iyi donusumu belirlemeyi amaclar. Donusum sonrasinda elde edilen degiskenler ilk degiskenlerin temel bilesenleri olarak adlandirilir.
Ilk temel bilesen varyans degeri en buyuk olandır ve diger temel bilesenler varyans degerleri azalacak sekilde siralanir.
Daha aciklayici bir degisle temel bilesen analizi, istatistikte cok boyutlu uzaydaki bir verinin daha dusuk boyutlu bir uzaya izdusumunu, varyansı maksimize edecek sekilde bulma yontemidir.
Temel Bilesenler Analizi;
- Veri kumelerinin boyutunu azaltmak(indirgemek),
- Yorumlanabilirligi arttirmak,
- Bilgi kaybini en aza indirmek icin kullanilir.
Modelde kullanilacak veri train ve test olarak ikiye ayrilir. Train seti ile model kurulur ve test seti uzerinden modelin performansi degerlendirilir.
Bu analizde kullanacagimiz veriyi gorelim;

df <- df[, -1]
view(df)Veriden kisaca bahsedecek olursak: 100 musteri icin urun musteri anketi verisini ele alacagiz. Burada bagimli degiskenimiz satisfaction degeridir. Yani biz burada memnuniyeti tahmin etmeye calisacagiz.
Ilk olarak verimizde eksik veri olup olmadigini kontrol etmekle baslayalim; Verimde eksik veri yok ama bu hatayi aldigim icin ve cozemedigim icin maalesef burayi silmek zorunda kaldim. #library(mice) #md.pattern(df) bu sekilde eksik veri kontrolu yaptik.
Error in (function (filename = “Rplot%03d.png”, width = 480, height = 480, : unable to start png() device
Eksik verimizin olmadigini gozlemliyoruz.
##VERİMİZİ TEST VE TRAİN OLARAK İKİYE AYIRMAKLA DEVAM EDECEGİZ
Veriyi ikiye ayirirkan belirli bir oran kullaniyoruz.
set.seed(145)
sampleIndex<-sample(1:nrow(df),size=0.8*nrow(df))
trainset<-df[sampleIndex,]
testset<-df[-sampleIndex,]
train_x<-trainset %>% dplyr::select(-Satisfaction)
train_y<-trainset$Satisfaction
test_x<-testset %>% dplyr::select(-Satisfaction)
test_y<-testset$Satisfaction
names(df)## [1] "ProdQual" "Ecom" "TechSup" "CompRes" "Advertising"
## [6] "ProdLine" "SalesFImage" "ComPricing" "WartyClaim" "OrdBilling"
## [11] "DelSpeed" "Satisfaction"Ayirdigimiz testset ve trainset icin ayri ayrı satisfactionlu ve satisfactionsuz veri olusturuyoruz.
Bagimsiz degiskenlerimizin birbiriyle olan iliskini gormek icin hisgorgam grafigi olusturalim;
#chart.Correlation(df%>%dplyr::select(-c(“Advertising”,“ComPricing”,“WartyClaim”)),histogram=TRUE,pch=19) Daha oncesinde hatasiz calistidigim ama markdown olarak kaydedecegim zaman bu sekilde bir hata aldim ve cozumunu bulamadigim icin bu sekilde yazmak durumunda kaldim. Grafigi inceledigimiz zaman alt tarafta yogun koyulasmis olan grafikleri goruyor olacaktik. Bu koyuluk baska degisle cizgi etrafindaki yogunluk bize bagimsiz degiskenlerin birbirleriyle olan iliskisinin fazla oldugunu gostermektedir. Error in (function (filename = “Rplot%03d.png”, width = 480, height = 480, : unable to start png() device
Veri icerisindeki bagimsiz degiskenlerin bazilarinin birbiriyle onemli derecede iliskisi gorulmektedir. Bu da bize multicolinearty problemiini isaret etmektedir.

R-Squared değerinin 0.7148 oldugunu goruyoruz. Bu sayinin 1 e yakin olması bizim istedigimiz seydir. Bu bize modelimizde bagimsiz degiskenlerin bagimli degiskeni aciklama yuzdesini verir. Degiskenlerimiz memnuniyet puanini %71 oraninda etkiler. Degiskenler memnuniyet puanini arttirmaktadir diye de yorumlayabiliriz.

Farkli train-test bolumleri sonucunda farkli accuarty degerleri elde edildigini ama bunlarin birbirine oldukca yakin oldugunu gozlemliyoruz. Accuracy degeri bizwe dogru tahmin etme oranini verir. Buyuk olmasini isteriz.
Her bir bilesen icin, MSEP hata metrigine ait degerler grafikteki gibidir.
MODEL KARSİLASTİRMASİ
Burada biz modelpcr ile modelpcr_cv modelini karsilastirarak nihai modele ulasacagiz.
Kolay yorumlayabilmek adina metrikleri kisaca tanimlayacak olursak ; RMSE= Gercek degerler ile tahmin edilen degerler arasindaki farkin ortalama buyuklugunu olcer. Rsquared = Gercek deger ile modelin tahminleri arasindaki uyumun bir olcusudur. MAE= Gercek gegerler ile tahmin edilen degerler arasindaki hatalarin mutlak degerlerinin ortalamasidir.
