    In statistical modelling the MSE can represent the difference between the actual observations and the observation values predicted by the model. In this context, it is used to determine the extent to which the model fits the data as well as whether removing some explanatory variables is possible without significantly harming the model's predictive ability.

  • Mean Absolute Error (MAE) and Root Mean Squared

    Expressing the formula in words, the difference between forecast and corresponding observed values are each squared and then averaged over the sample. Finally, the square root of the average is taken. Since the errors are squared before they are averaged, the RMSE gives a relatively high weight to large errors. This means the RMSE is most useful when large errors are particularly undesirable.

In any case, if I look at contingency tables, then the chi-square test is indeed impacted by multiplying all the columns by a constant or adding a constant to all the columns.

  • Stoping - Wikipedia

    Stoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.. The earliest forms of stoping were conducted with hand tools or by fire-setting; later gunpowder ...
