%description
Companion package of Carrion-i-Silvestre & Sansó (2023): "Generalized
Extreme Value Approximation to the CUMSUMQ Test for Constant Unconditional
Variance in Heavy-Tailed Time Series". It implements the Modified
Iterative Cumulative Sum of Squares Algorithm, which is an extension of
the Iterative Cumulative Sum of Squares (ICSS) Algorithm of Inclan and
Tiao (1994), and it checks for changes in the unconditional variance of a
time series controlling for the tail index of the underlying distribution.
The fourth order moment is estimated non-parametrically to avoid the size
problems when the innovations are non-Gaussian (see, Sansó et al., 2004).
Critical values and p-values are generated using a Generalized Extreme
Value distribution approach. References Carrion-i-Silvestre J.J & Sansó A
