How to perform Heteroscedasticity test in STATA for time
Oct 16, 2018White test for heteroscedasticity . To check heteroscedasticity using White test, use the following command in STATA: estat imtest, white. The below results will appear.

Running Breausch-Pagan test and White test on Stata 14.0
Aug 12, 2017(I am using STATA version 14.0) I went to findit hettest to try to install if it is the case that the Breausch-Pagan test is not installed, but I am not being able to find an executable file to install (if it is the case). The same applies to the White test.

Test for Heteroskedasticity with the White Test - dummies
When you plug this information into STATA (which lets you run a White test via a specialized command), the program retains the predicted Y values, estimates the auxiliary regression internally, and reports the chi-squared test. The figure shows the resulting output, which suggests you should reject the homoskedasticity hypothesis.[PDF]

How can I perform the likelihood ratio and Wald test in
UsesExampleDefinitionAnalysisThe likelihood ratio (lr) test and Wald test test are commonly used to evaluate the difference between nested models. One model is considered nested in another if the first model can be generated by imposing restrictions on the parameters of the second. Most often, the restriction is that the parameter is equal to zero. In a regression model restricting a parameters to zero is accomplished by removing the predictor variables from the model. For example, in the models below, the model with the predictor variSee more on stats[PDF]

Doctors prescribe the ALT test,sometimes in conjunction with other tests,to identify the cause of high SGPT levels in their patients. Role of the Liver. The liver plays an important role in many daily functions.What Does High SGPT Mean? | ReferenceSee all results for this questionHow to check for heteroskedasticity?How to check for heteroskedasticity?To checkforheteroscedasticity, you need to assess the residuals by fitted value plots specifically. Typically, the telltale pattern for heteroscedasticityis that as the fitted values increases, the variance of the residuals also increases. You can see an example of this cone shaped pattern in the residuals by fitted value plot below.Heteroscedasticity in Regression Analysis - Statistics By JimSee all results for this questionWhat is heteroskedasticity in econometrics?What is heteroskedasticity in econometrics?In econometrics,the autoregressive conditional heteroskedasticity (ARCH) model is a statistical model for time series datathat describes the variance of the current error term or innovation as a function of the actual sizes of the previous time periods' error terms; often the variance is related to the squares of the previous innovations.Autoregressive conditional heteroskedasticity - WikipediaSee all results for this question
