onlineregression12c:   One-predictor-variable nonlinear regression (max input 3000 characters)    ⇒   rating curve   Q = f(H)


Formulas

Q= aHb         log(Q)= log(a) + b[log(H)]

u= log(H)        v= log(Q)         v= log(a) + bu

v= α + βu         log(a)= α        b= β        a= 10α

β= [Σ(uv)-(ΣuΣv)/n]/{Σ(u2)-[(Σu)2/n]}

α= [Σv-(βΣu)]/n        Q = 10αHβ

Reference


INPUT DATA:

Enter array size n:     

Enter paired values of arrays y and x (separate each value with a comma; maximum string length is 3000 characters).

Q:     

H:     


ECHO OF INPUT:

n =  

Q(1) =  .   

H(1) =  .   


OUTPUT:

a =            b =            Q = H
