Check out the LINEST and LOGEST functions. LINEST's name and
documentation are misleading. For more on how to use it for non-linear
regressions see Bernard Liengme's
Polynomial regression. How can I fit my X, Y data to a polynomial using
LINEST?

i need to run repeated regressions on a large set of data, and put the
resulting values in a table for each column of data in my set. however, i
don't want to repeat the regression function in the data analysis toolpack
and cut/paste the relevant data into my table, 50 times.
anyone know how to do this
