simple data modeling tool

step 1: specify data structure

x_i   y_i   (measurements without estimated errors; i = 1..N)
x_i   y_i   dy_i   (measurements with estimated errors; i = 1..N)

step 2: supply data

enter values separated by blanks and/or newlines ordered as indicated in step 1

1 -1.38 2 -0.49 3 -1.20 4 0.73 5 1.72 6 4.00 7 2.47 8 3.88 9 6.10 10 6.26

step 3: chose model components

a₀ (constant term)   a₁ x (linear term)   a₂ x² (quadratic term)

step 4: fit model to data
