41. Percentage regression is linked to a multiplicative error model, whereas OLS is linked to models containing an additive error term . 42. The inner controller's error term is the difference between this heater temperature setpoint and the measured temperature of the heater. 43. That is, a component that is linear in the interest rate changes plus an error term which is at least quadratic. 44. Unlike the Strict exogeneity with respect to the idiosyncratic error term u _ { it }, however, is still required. 45. Split-plot designs have more than one size experimental unit, i . e ., more than one error term . 46. In regression analysis, " heteroscedasticity " refers to unequal variances of the random error terms ? i, such that 47. Also in a linear regression model the non deterministic part of the model is called error term , disturbance or more simply noise. 48. Note that the derivative of " & fnof; " in the error term increases by 2 for every other rule. 49. That is, the error term " A t " is assumed to follow the assumptions for a stationary univariate process. 50. Fitting the MA estimates is more complicated than with autoregressive models ( AR models ) because the lagged error terms are not observable.
