  2. Environmental error - Wikipedia

    en.wikipedia.org/wiki/Environmental_error

    Any experiment performing anywhere in the universe has its surroundings, from which we cannot eliminate our system. The study of environmental effects has primary advantage of being able us to justify the fact that environment has impact on experiments and feasible environment will not only rectify our result but also amplify it.

    en.wikipedia.org/wiki/List_of_model_checking_tools

    In 1999, Judi Romijn compared two model checkers (CADP and SPIN) on the HAVi interoperability audio-video protocol for consumer electronics. [3] In 2003, Yifei Dong, Xiaoqun Du, Gerard J. Holzmann, and Scott A. Smolka published a comparison of four model checkers (namely: Cospan, Murphi, SPIN, and XMC) on a communication protocol, the GNU i ...

    Any non-linear differentiable function, (,), of two variables, and , can be expanded as + +. If we take the variance on both sides and use the formula [11] for the variance of a linear combination of variables ⁡ (+) = ⁡ + ⁡ + ⁡ (,), then we obtain | | + | | +, where is the standard deviation of the function , is the standard deviation of , is the standard deviation of and = is the ...

    One can then also calculate the mean square of the model by dividing the sum of squares of the model minus the degrees of freedom, which is just the number of parameters. Then the F value can be calculated by dividing the mean square of the model by the mean square of the error, and we can then determine significance (which is why you want the ...

  7. Autoregressive conditional heteroskedasticity - Wikipedia

    The lag length p of a GARCH(p, q) process is established in three steps: . Estimate the best fitting AR(q) model = + + + + = + = +. Compute and plot the ...

  8. Nash–Sutcliffe model efficiency coefficient - Wikipedia

    en.wikipedia.org/wiki/Nash–Sutcliffe_model...

    The Nash–Sutcliffe coefficient masks important behaviors that if re-cast can aid in the interpretation of the different sources of model behavior in terms of bias, random, and other components. [11]

  9. Linear regression - Wikipedia

    en.wikipedia.org/wiki/Linear_regression

    To check for violations of the assumptions of linearity, constant variance, and independence of errors within a linear regression model, the residuals are typically plotted against the predicted values (or each of the individual predictors).
