(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Show that the calculation of an arithmetic mean for a given set of values y1,y2....yn is equivalent to fitting the line y=y_av to the data under the least square criterion

2. Relevant equations

distance between the data points and the best fit curve:

[tex]d(y_n,f(x))= \Sigma_{i=1}^{n}(y_i-f(x_i,a_1,a_2,...,a_n))^2[/tex]

arithmetic mean of a set of values y_n:

[tex]y_av= \frac{1}{n} \Sigma_{i=1}^{n}y_i[/tex]

3. The attempt at a solution

I need help getting started please!
