Press to view regressions.

Press to select
linear regression which finds the best-fit
linear equation of the form y = ax + b.

Press to select
med-med regression which finds another best-fit
linear equation of the form y = ax + b.

Press to select
quadratic regression which finds the best-fit
quadratic equation of the form y = ax^{2} + bx + c.

Press to select
cubic regression which finds the best-fit
cubic equation of the form y = ax^{3} + bx^{2} + cx + d.

Press to select
quartic regression which finds the best-fit
quartic equation of the form y = ax^{4} + bx^{3} + cx^{2} + dx + e.

Press to select
logarithmic regression which finds the best-fit
logarithmic equation of the form y = a + b ln x.

Press to select
exponential regression which finds the best-fit
exponential equation of the form y = ae^{bx}.

Press to select
power regression which finds the best-fit
power equation of the form y = ax^{b}.

Press to select
sinusoidal regression which attempts to finds an approximating equation of the form
y = a sin(bx+c) + d.

Press to select
logistic regression which attempts to finds an approximating equation of the form
y = c / (1 + ae^{-bx}).
