What causes heteroskedasticity?
Heteroskedasticity is when the standard deviation of a variable is inconsistent when measured several times over a period of time.
How can one test for heteroskedasticity in a statistical analysis?
One way to test for heteroskedasticity in a statistical analysis is to use the Breusch-Pagan test or the White test. These tests examine the relationship between the error terms and the independent variables in a regression model to determine if the variance of the errors is constant. If the test results show that the variance is not constant, it indicates the presence of heteroskedasticity.

What are the factors that affecting the quality of data?
Trends, covariance, and correlation are the big ones. Statistical significance, unit roots, heteroskedasticity, and format and source of the data would affect quality too.
What is a power ARCH model?
A power ARCH (PARCH) model is a type of econometric model used to analyze and forecast time series data, particularly in financial markets, where volatility is often not constant. It extends the traditional ARCH (Autoregressive Conditional Heteroskedasticity) model by allowing for asymmetric effects of shocks on volatility and incorporating power transformations. This flexibility helps capture varying degrees of volatility clustering and leverage effects, making it suitable for modeling asset returns that exhibit such behaviors. PARCH models are valuable in risk management and derivative pricing, providing deeper insights into market dynamics.
