11. A variety of methods are available to estimate non-linear models . 12. Cinematch uses " straightforward statistical linear models with a lot of data conditioning ". 13. A linear model can be derived from IPC that tracks the OS routine power. 14. Each log-linear model can be represented as a log-linear equation. 15. The linear models of innovation supported numerous criticisms concerning the linearity of the models. 16. In non-linear models the direction of the bias is likely to be more complicated. 17. So, something like fitting a general linear model to observed data is a statistical model. 18. The Cox PH regression model is a linear model . 19. Generalized linear models were formulated by John Nelder and variance stabilized responses, have been developed. 20. The regression model then becomes a multiple linear model :
