In scenarios with lower accuracies, the balance of increasing genetic variance from changing allele frequencies and decreasing variance from selection resulted in a small increase of variance.
Inbreeding, and to a small extent selection, reduced the additive genic variance and therefore also the additive genetic variance by changing the allele frequencies of causative loci.
D2 describes the relative model variance reduction changing from a random-effects model into a fixed-effect model.
Spatial biodiversity, in turn, covers the occurrence of species in a given region or habitat, which is essential to predict species variance with changing environmental and climatic conditions.
A RF will be an adjustment of N F to N R taking into account the total variance expansion changing from a fixed-effect into a random-effects model.
Four situations regarding the additive noise are considered: stationary context with fixed variance and possible outliers and non-stationary context with changing variance and possible outliers.

The situation is considerably better if the RV that defines the variance of the random process is itself generated by a random process, producing a slight change at every time instant so as to slowly modify the signal's variance over time, as is commonly done to resemble speech signals with their slowly changing variance.
As we mentioned early, high-frequency financial data, like our BUX stock time series, reflect a stylized fact of changing variance over time.
For example, stretching PD i (f) over time would automatically reduce its temporal variance and thus, changing the extent of randomness in the voice, which is not the purpose of a time stretching transformation.
