George Box. The phrase "all models are wrong" was first attributed to George Box in a 1976 paper published in the Journal of the American Statistical Association.In the paper, Box uses the phrase to refer to the limitations of models, arguing that while no model is ever completely accurate, simpler models can still provide valuable insights if applied judiciously.

In statistical quality control, the individual/moving-range chart is a type of control chart used to monitor variables data from a business or industrial process for which it is impractical to use rational subgroups.
Graphical statistical methods have four objectives: [2] The exploration of the content of a data set; The use to find structure in data; Checking assumptions in statistical models; Communicate the results of an analysis. If one is not using statistical graphics, then one is forfeiting insight into one or more aspects of the underlying structure ...
The name Kura Te Au originates from the red colour of the sea caused by a variety of plankton and the high populations of crustacean krill. According to legend, Kura Te Au is where Kupe killed the giant, mythical octopus, Te Wheke-a-Muturangi, causing its blood to run through the channel, turning the water red.
Software packages usually default to a homoscedastic model, even though such a model may be less accurate than a heteroscedastic model. One simple approach ( Tofallis, 2008 ) is to apply least squares to percentage errors, as this reduces the influence of the larger values of the dependent variable compared to ordinary least squares.
In statistical process control (SPC), the ¯ and R chart is a type of scheme, popularly known as control chart, used to monitor the mean and range of a normally distributed variables simultaneously, when samples are collected at regular intervals from a business or industrial process. [1]
In Māori mythology, Te Wheke-a-Muturangi is a monstrous octopus destroyed in Whekenui Bay, Tory Channel or at Patea by Kupe the navigator. The octopus was a pet or familiar of Muturangi, a powerful tohunga of Hawaiki. The wheke was nonetheless a wild creature and a guardian. When Kupe reached New Zealand, he encountered the beast off Castlepoint.
Indeed, minimizing AIC in a statistical model is effectively equivalent to maximizing entropy in a thermodynamic system; in other words, the information-theoretic approach in statistics is essentially applying the second law of thermodynamics. As such, AIC has roots in the work of Ludwig Boltzmann on entropy.
