If you fit your model with the gam function in the mgcv package, you can see that the model summary reports the estimated value of σ 2. For example:

WebThe Additive Component If the multiplicative component is set equal to one, the linear transformation becomes X' = a + X, so that the effect of the additive component may be examined. With this transformation, a constant is added to every score. An example additive transformation is shown below: Linear Transformation where a=20, b=1 X X' = a … Webadditive: [adjective] of, relating to, or characterized by addition.

If the standard deviation is big, then the data is more "dispersed" or "diverse". As an example let's take two small sets of numbers: 4.9, 5.1, 6.2, 7.8 and 1.6, 3.9, 7.7, 10.8 The average (mean) of both these sets is 6.

WebThe amount of time it takes each employee to inspect the item has a mean of 30 30 seconds and a standard deviation of 6 6 seconds. Furthermore, the amount of time it takes a given employee to inspect an item is not impacted by how long it takes another employee to inspect that item. WebBecause i was curious, i wanted to know the average monthly mean power, and its standard deviation. Through induction, we need 12 normal distributions which: sum to a mean of 10,358; sum to a variance of 647,564; That would be 12 average monthly distributions of: mean of ; variance of ; standard deviation of sqrt(53963.6) = 232.3

WebThe Standard Deviation is Sub-Additive A sub-additive risk measure ρ[X] satisfies the following: ρ[X + Y] # ρ[X] + ρ[Y] A super-additive risk measure satisfies: ρ[X + Y] $ ρ[X] + ρ[Y] When only equality holds, the risk measure is additive.
