Your procedure for fitting your data is, of course, nonsense: the way to fit points with errors is to input them into a suitable fitting program. For a simple straight line fit, curve_fit might be considered overkill, but it does work: with your (silly) errors, it gives a gradient of 0.050± 0.019 THz T−1, which corresponds to a

The last one, (ir.f_), is an interpolating function which can be evaluated in the domain [xmin, xmax]. ... this can result in over-fitting. Always plot the relationships to see the fit and focus on making sure that the curve fits the nature of the problem. Here is an example of how plotting ...

All curve fitting procedures including data preprocessing and curve fitting were implemented in Python 2.7 with scipy, numpy 29, matplotlib 33 and lmfit libraries 34. Image analysis Based on 12 (~3-4 plaques taken from each sample) images showing the spatial distribution of β-sheets, our computations aimed at the determination of four ~4 ...

Staff plans to use the emissions data (item 2 above) to programmatically estimate a best-fit curve for each plant using the Python programming language (specifically, the Pandas, Numpy, and Scipy packages). This curve will show the relationship between emissions rates (lbs Nox / mmbtu of fuel burn) versus operating level (% of nameplate MW).

Currently a curve is fitted to the raw test data using a combination of filtering and a least squares method. In order to more intelligently fit our data to material models we wish to investigate the use of fitting splines to our data, controlling the shape of the curve using derivatives, controlling knots, number of polynomes, smoothness ...

In the latter method, an estimate of fractal dimension (between 1 and 2) is calculated by fitting to select height isopleths and/or to the coastline curve. A large fractal dimension implies complex topography, while values close to 1 indicate an almost flat domain (Jaggi et al, 1993).
Using Python in Introductory Physics
The libraries you will need for these exercises are Numpy, Scipy, and MatPlotLib, which are often known collectively as "pylab". If you are already using Python, you may have these packages already; or you may need to do a more customized installation. If not, the simplest way to install what you need is to install "Anaconda".

What curve_fit does can be extracted from its entry in the SciPy reference manual: it uses the Levenberg-Marquardt algorithm in a non-linear least squares fit. There are many possible references for Levenberg-Marquardt: the Wikipedia entry gives the original papers by Levenberg and Marquardt and a number of secondary references.
