WebNov 5, 2024 · A standard identifiability condition asks the coefficient θ to be less than 1. Nevertheless, if in my model θ > 1. For example, in the problem considered here: Superposition of random walk and autoregressive process Therefore, θ is parametrised in a way that it must be greater than 1. WebThis can lead to unstable and unreliable estimates of the regression coefficients. One way to detect collinearity is to calculate the variance inflation factor (VIF) for each independent variable. A VIF value of 1 indicates no collinearity, while values greater than 1 suggest increasing levels of collinearity. csu northridge supplemental applicationWebFrom Table 2 although there is no close analogous statistic in logistic regression to the coefficient of determination , Table 2 provides some approximations.
