The resulting curve is shown in Figure 12.1A. The abscissal axis is divided into multiples of σ values; thus, +1 or −1 refers to values that are within one standard deviation either greater than or less than the mean. It is useful to consider the area under the curve at particular...
stress analysisexperimental mechanicsIn the Gaussian curve method, a simplified equation for calculating the standard deviation(s.d.) σ_p of a peak position p is derived to reveal factors affecting σ_p. Equations for evaluating a diffraction line width were also derived in the Gaussian curve ...

9.4 is plotted with a dashed curve corresponding to the best fitting instance of this density function, with the parameters {s, p} estimated by maximizing the probability of the data under the model. The density model fits the histograms remarkably well, as indicated numerically by the relative...
I have some data that I have binned with thehistfunction. I am trying to fit a Gaussian function to the histogram data, and I noticed that the parameterc1of the Gaussian fit in theCurve Fitting Appdoes not correspond to the standard deviation of a ...

Judea Pearl said that much of machine learning is just curve fitting1— but it is quite impressive how far you can get with that, isn’t it? In this blog post, we will look at the mother of all curve fitting problems: fitting a straight line to a number of points. In doing so, ...
For example, if 1.4m is the height of a school pupil where the mean for pupils of his age/sex/ethnicity is 1.2m with a standard deviation of 0.4 then z = (1.4-1.2) / 0.4 = 0.5, i.e. the pupil is half a standard deviation from the mean (value at centre of curve). The ...
