Further Examples: Fit

Here is a list of points.

In[1]:=

Here is a plot of points.

In[2]:=

This fits the data to a straight line with x intercept -2.

In[3]:=

Out[3]=

This plots the line.

In[4]:=

This shows the line together with points.

In[5]:=

Here is a table of the sum of the squares of the divisors of the first positive integers.

In[6]:=

Out[6]=

Here is a plot of divisorsigma2table.

In[7]:=

Here are linear and quadratic fits to divisorsigma2table.

In[8]:=

Out[8]=

In[9]:=

Out[9]=

Here are the plots of the linear and quadratic fits.

In[10]:=

This shows the linear and quadratic fits superimposed on the original data. The quadratic fit is better than the linear one.
