# Upper And Lower Limits Of Agreement

Suppose X1, …, X N is a sample of a population N (μ, 2) of an unknown average μ and variance 2 for N > 1. The sample average ””superline”” and the variance of the S2 sample are defined as ”value,” ”Limits_” and ”limits_” ”_i”_i limits_” Distribution centile N (μ, 2) is referred to as KupperL, Hafner KB. How appropriate are the sample size formulas? At the 1989 Stat. The simple 95% limits of the agreement method are based on the assumption that the average value and standard deviation of differences are constant, i.e. they do not depend on the size of the measurement. In our original documents, we described the usual situation where the standard deviation is proportional to size, and described a method using a logarithmic transformation of the data. In our 1999 review paper (Bland and Altman 1999), we described a method to avoid any relationship between the average and the SD of the differences and magnitude of the measurement. (It was Doug Altman`s idea, I can`t take recognition.) On the other hand, in establishing confidence intervals between the boundaries of agreements or percentiles, Bland and Altman  argued that var[S] ≐ 2/(2) and Var [2) and Var [2) B] ≐ b-2/N, the B-1-for example _p. As they got closer, they proposed the simplified rotational speed of Figure 27.31. Bland-Altman chart with 95% confidence limits with a gradual increase in difference and heteroskedasticity.
