...r[2]-(x/number[1])^number[3]
Number [2] and number [1] change as the data changes but for all the set of
data number[3] must be identical.
I have 3 set of data (x1,y1), (x2,y2), (x3,y3).
x_a<-c(0,0.5,1,1.5,2,3,4,6)
y_a<-c(5.4,5,4.84,4.3,4,2,1.56,1.3)
x_b<-c(0,1,2,3,4,5,6,7,8,9,10,11,12)
y_b<-c(5.34,4.98,4.66,4.06,3,3.4,2.7,2.9,2.6,2.6,1.9,1.3,1.4)
x_c<-c(0,3,6,8,10,12,14,16,18,20,24,26,28,30)
y_c<-c(5.5,5.1,4.3,4,3.7,3.2,3.04,2.778,2.56,2.25,1.78,1.44,1.32,1.2)
x<-c(x_a,x_b,x_c)
y<-c(y_a,y_b,y_c)
long<-c(0,8,21,35)
Hence, the sum of squares is:
