A note on testing for homoscedasticity in high-dimensional time series
We consider the problem of testing for homoscedasticity in high-dimensional time series, under the assumption that the sample size n and the dimension p satisfy [Formula: see text] as [Formula: see text]. The homoscedasticity refers to the case where the covariance matrix of the time series is equal...
