In this study, a univariate Weibull regression model is discussed. The developed from the distribution, that distribution depending on covariates or parameters. (UWR) can involve survival function and mean of response variable with scale parameter stated in terms aim study to estimate UWR parameters using maximum likelihood estimation (MLE) method, test result shows closed form estimator not be found analytically, it approximed by Newton-Raphson iterative method. testing involves simultaneous partial test. statistic for Wilk's ratio. Wilk follows Chi-square which derived ratio (LRT) Wald standard normal distribution. alternative statistik squared statistic, where one degree freedom.
