This tool will compute doubling time of a time serie. It uses a last square
fitting exponential method cited below.
Paste your data in the
following box. Copy-paste from Excel works fine.
Curve fitting equations are used to fit your data to a theoritical curve.
Several methods exist to do this job.
One method, first transforms your data into a line, then applies to this
line the
least squares fitting method. Another method (the one used here), applies least square fitting method
directly to your data. This method was used because it weights the data
points equally. You will find some explanations with an example plot
here.
