«(assuming Gaussian errors in observable parameters, which is approximately equivalent to a uniform «prior» in feedback parameter)»
I would agree with that, if there was some a priori knowledge that in fact the plotted function was known to actually be a straight line buried in Gaussian random noise.
If the temperature anomaly follows a normal Gaussian curve, the number of data points that are more than one standard deviation (abbreviated as σ) from the average can be calculated.
Figure 1: Reconstructed tropical South American temperature anomalies (normalized to the 1961 — 1990AD average) for the last 1600 years (red curve, smoothed with a 39 ‐ year Gaussian filter).
In build 17035, the touch keyboard experience includes Acrylic, an element from the Fluent Design System where the light and colors from the desktop illuminate through the surface of the app in a new form of transparency that is made of Gaussian blur, exclusion blend, color / tint overlay, and tiled noise texture.
Analysis shows that machine learning methods based on Gaussian process regression can be applied to all the wines in the Liv - ex 100 with an improvement in average predictive accuracy of 15 % relative to the most effective of the traditional methods.
In all cases the optimal waveform was a truncated Gaussian pulse — a bell curve with a vertical line cutting short the lower parts of each.
Threshold was determined by fitting bimodal distributions of intensity values with two peak Gaussian functions.
In many simple contexts, one can get away with interpreting frequentist confidence intervals as if they were summarizing a Bayesian posterior distribution of roughly Gaussian form, in which the probability density for points outside the confidence interval declines fairly rapidly as one moves away from the endpoints.

They did preliminary testing of the system on with classification of ten bird species native to India carried out using Gaussian Mixture Modelling (GMM) and Support Vector Machines (SVMs).
Briffa's analysis assumes roughly Gaussian noise and roughly linear temperature response after adjusting for age.
The sizes of the estimated autocorrelations of the proportion of male births are similar to those of a simulated time series of 360 independent, zero - mean Gaussian observations, or white noise (Fig. 4C).
The case for non-standardized gaussian variables is more complex and is dealt with by using transformations and / or approximations.
Actually the cylindrical - Earth approximation makes everybody happy: the flat - Earthers because Gaussian curvature vanishes, but also the non-nutters as mean curvature is positive...
To understand the principle behind robust statistics, Moitra explains, consider the normal distribution — the bell curve, or in mathematical parlance, the one - dimensional Gaussian distribution.
Generally, this is how a normal (also called Gaussian) distribution looks like:
Due to short term variation and the noise being amplified by the differentiation, a 24 month gaussian filter has been applied after differentiation (48m in the case of 2nd differential.)
In the regularized EM algorithm, a regularized estimation method replaces the conditional maximum likelihood estimation of regression parameters in the conventional EM algorithm for Gaussian data.
