Sentence examples for a decline in variance from inspiring English sources

For example, Galton's "regression to the mean" is defined as a decline in variance over generations (p. 102), which is misleading for modern readers.

Therefore, this suggests a decline in variance in age-at-death or the process of compression of mortality over the time period (36, 46, 49).

Our evidence suggests that the ex ante risk premium on the global market portfolio has dropped considerably - we show that this fall in the risk premium is related to a decline in the conditional variance of global real cash flow growth rates.

Scatter plots in previous studies of sperm TL versus the donor's age (Allsopp et al., 1992; Baird et al., 2006; Aston et al., 2012) display no evidence for a decline in sperm TL variance with age, but sample sizes were relatively small to fully exclude a 'ceiling effect' for sperm TL dynamics.

Those with non-epithelioid histology had a decline in HRQoL and the variance from baseline between the groups was significant, although the same pattern was seen in the comparator group (see Figure 1).

Although reductions in prereproductive mortality drove the decline in variance in relative total fitness, we observed an increase in the variance of relative fertility (up to 1974, 5.57; 1975 onward, 6.32; ρ = +0.49; p < 0.001; Figure 1C), a pattern that also marks the first stages of other demographic transitions [ 2, 10, 13].

The highest decline in variance over the next 5 years occurred in the expected number of years lived adjusted only for dispersion (e C ).

Importantly, we did not find evidence for the decline in overall selective pressures across the demographic transition that could be expected from observing the decline in variance in relative total fitness with time.

The decline in variance in relative fitness was mostly explained by the decrease in variance in relative child survival (up to 1974, 5.20 × 10−2; 1975 onward, 8.15 × 10−3; ρ = −0.84; p < 0.001; Figure 1B), itself the result of the decrease in mean child mortality.
