A sequence of variables in which each variable has a different variance. Heteroscedastics may be used to measure the margin of the error between predicted and actual data.
variables
There are various tests for heteroscedasticity. For bi-variate data the easiest is simply plotting the data as a scatter graph. If the vertical spread of the data points is broadly the same along its range then the data are homoscedastic and if not then there is evidence of heteroscedasticity. Heteroscedasticity may be removed using data transformations. The appropriate transformation will depend on the data and there is no general transformation that will work in all instances.

Yes, they are the same.
In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.
Autocorrelation can lead to biased parameter estimates and inflated standard errors in statistical models. It violates the assumption of independence among residuals, potentially affecting the accuracy of model predictions and hypothesis testing. Detecting and addressing autocorrelation is essential to ensure the validity and reliability of statistical analyses.

Error
Unfortunately, there are also some problems with the use of the autocorrelation. Voiced speech is not exactly periodic, which makes the maximum lower than we would expect from a periodic signal. Generally, a maximum is detected by checking the autocorrelation
