Question

Quizplus · Accepted Answer

Time series data often exhibits autocorrelation, which means that the values in the series are correlated with each other over time. This is because each value in the series is dependent on previous values. Homoscedasticity and heteroscedasticity refer to the level of variance in the data and may or may not be present in time series data. Multicollinearity refers to the presence of highly correlated predictor variables in a regression model and is not relevant to time series data.
