Vektor

Cara membuat data dalam vektor. `

#create sampel data 
X <- c(15, 17, 19, 20, 22, 34, 25, 50)
Y <- c(150, 200, 235, 220, 267, 300, 310, 400)
#print sample 
X
## [1] 15 17 19 20 22 34 25 50
Y
## [1] 150 200 235 220 267 300 310 400

simple Linier Regression

Y = a + bx

Y = 170 + 17X

Scatter Plot

plot(Y - X, ylab="Y" ,  pch=20 )

#systematic Relationship to the plot 

abline(a =310, b=-40)
