Symmetry Analysis of the Uncertain Alternative Box-Cox Regression Model

چکیده
The asymmetry of residuals about the origin is a severe issue in estimating Box-Cox transformed model. In framework uncertainty theory, there are such theoretical issues regarding least-squares estimation (LSE) and maximum likelihood (MLE) linear models after transformation on response variables. Heretofore, only weighting methods for analysis have been available. This article proposes an uncertain alternative model to alleviate avoid λ tending negative infinity LSE or MLE. Such symmetry reasonable applications experts’ experimental data. parameter method was given via theorem, performance our supported numerical simulations. According simulations, proposed ‘alternative model’ can overcome problems grossly underestimated lambda residuals. estimated neither deviated from zero nor changed unevenly, clear contrast MLE downward biased Thus, though not applicable model, they fit Compared with systematically likely occur Both be used directly without constructing weighted method, offering better

Implementing Box-Cox Quantile Regression∗
The Box-Cox quantile regression model introduced by Powell (1991) is a flexible and numerically attractive extension of linear quantile regression techniques. Chamberlain (1994) and Buchinsky (1995) suggest a two stage estimator for this model but the objective function in stage two of their method may not be defined in an application. We suggest a modification of the estimator which is easy to...
متن کاملSome Alternatives to the Box- Cox Regression Model
A nonlinear regression model is proposed as an alternative to the Box-Cox regression model for nonnegative variables. The functional form contains as special cases the linear, exponential, constant elasticity, and generalized CES specifications, as well as other functional forms used by applied econometricians . The model can be derived from but is more general than a particular modification of...
متن کاملPenalized Estimators in Cox Regression Model
The proportional hazard Cox regression models play a key role in analyzing censored survival data. We use penalized methods in high dimensional scenarios to achieve more efficient models. This article reviews the penalized Cox regression for some frequently used penalty functions. Analysis of medical data namely ”mgus2” confirms the penalized Cox regression performs better than the cox regressi...
متن کاملalternative for the cox regression model: using parametric models to analyze the survival of cancer patients
background: although the cox proportional hazard regression is the most popular model for analyzing the prognostic factors on survival of cancer patients, under certain circumstances, parametric models estimate the parameter more efficiently than the cox model. the aim of this study was to compare the cox regression model with parametric models in patients with gastric cancer who registered a...
متن کاملModel assisted Cox regression
Semiparametric random censorship (SRC) models (Dikta, 1998), derive their rationale from their ability to gainfully utilize parametric ideas within the random censorship environment. An extension of this approach is developed for Cox regression, producing new estimators of the regression parameter and baseline cumulative hazard function. Under correct parametric specification, the proposed esti...
