Fill in the following information to generate
data for problems in least squares data fitting.
See the comments below for further information:
Note:
The precision of the random x-values, and the derived
y-values, are goverened by the precision of xmax and ymax respectively.
In other words, if you want integers, put integer values in xmax and
ymax.
The y-values are not entirely random, they are generated by adding
white noise (uniformly random floating point numbers) to a linear
function with randomly generated slope and intercept.
You can regenerate the data at any time.
A popup java based calculator, with some statistical extensions,
has been built to assist in some of the computations. It can be found
by selecting the hyperlink at the bottom of the page.
