Fitting models to data:

Model fitting

• simple linear (fitting a line: b0 + b1*x)
• multiple linear (fitting a linear combination of x terms: b0 + b1*x1 + b2*x2 + ... + bn*xn)
• polynomial (fitting a polynomial, b0 + b1*x + b2*x**2 + ... + bn*x**n)
• non-linear (fitting an arbitrary function f(x), e.g., (vmax*x) / (km+x), dose*exp(-k*t)
• logistic (fitting the logit of y by a linear combination of x terms: b0 + b1*x1 + b2*x2 + ... + bn*xn)
