### Best Error Function for Areas with Larger Slopes

The first idea to come to mind is: $$\sum_{i=1}^n \bigg[\big(y_i-\hat y_i\big)^2 + \bigg\vert\dfrac{ d\hat y }{ dx }\bigg\vert \big(y_i-\hat y_i\big)^2 \bigg]$$ This gives you the regular square ...

### Adjust results for a systematic error

You can create many, say $n$, test samples, each of size e.g. 500, like yours, and measure the error for each of them. This gives you a sample of size $n$ of your systematic error and from that, you ...

### Absence and presence of uncertainties in a data

It looks like the uncertainties are reported out to two decimal places. If the uncertainty is so small that rounding to two decimal places gives zero, then I could see why they might choose against ...

The "total error" you are looking for may be something like the distance between functions. You are currently computing: $$error = \Sigma (f(x_i) -g(x_i))^2$$ This will, as you have found, ...
