why exponential model may be better choice for modelling data than the linear model.

  • engineering - ,

    If the change of something tends to be proportional to its present value, exponential fit works best.

    dx/dt = k x

    dx/x = k dt

    ln x = k t + c

    e^ln x = e^(kx+c)

    x = e^kx * e^c

    x = C e^kx
