Confidence intervals for geometric mean AMA1 antibody levels (µg / mL) were estimated by using log10 - transformed values, calculating the 95 % confidence interval based on the normal distribution, and then converting the limits to the original scale for presentation.

Projecting future wealth and known future income streams can be a good starting point for estimating a future marginal tax rate (e.g., what will tax rates be for the retiree who already has Social Security benefits, portfolio interest and dividends, real estate or other passive income sources, and / or Required Minimum Distributions [RMDs]-RRB-, but clearly some uncertainty remains, not the least because Congress could just outright change the tax laws between now and then (although even higher tax rates in the future is not a guarantee that Roth conversions are a good idea today!).

Therefore I submit that in order to estimate the distribution of the temperature anomalies for estimating temperature variability during some time span (perhaps each decade, or a set of 11 - year periods like Hansen et al.), then for each time span computed, then baseline for anomaly calculation should be equal to the time span being analyzed.

Because these independent proxy estimates of MAT are statistically indistinguishable from each other (Table 1), we combined all of the estimates into a joint distribution that was then resampled using a bootstrap technique (see Appendix).

If you then have evidence that includes (1) a shift in the central tendency and (2) increasingly frequent observations of events going over x sigma, over some decent sample of space or time or both and based on the best estimated shape of the original distribution, then it is at the very least, reasonable to assume that the former tails have shifted + / - in concert with the rest of the distribution; that is to say, the entire original distribution has shifted.

In our estimate, we hypothesized a wartime changeover to about 75 % engine inlet, with business as usual after the war, then gradually going to the 1970 distribution of Kent et al 2007.
