R help - Feb 2005 - nonlinear least square fit of an unknown function

Hi, I have a set of twelve points and wonder how I can
get a function that can then be used to calculate the
area under the curve (most important). Thanks.

Hi Eric,
if I understand you question,  are you trying to fit
an unknown distribution? Are looking for computing
theorical frequencies (area under the curve)?
In this case you could see:
http://cran.r-project.org/doc/contrib/Ricci-distributions-en.pdf
Use hist() and density() to identify your distribution
and then fit parameters.
Another way could be using splines (?spline).
Hoping I helped you.
Cordially
Vito

Top 10 reasons to become a Statistician

     1. Deviation is considered normal
     2. We feel complete and sufficient
     3. We are 'mean' lovers
     4. Statisticians do it discretely and continuously
     5. We are right 95% of the time
     6. We can legally comment on someone's posterior distribution
     7. We may not be normal, but we are transformable
     8. We never have to say we are certain
     9. We are honestly significantly different
    10. No one wants our jobs
