If one rater is usually higher or under programming other by desktop technological know-how constant amount, programming bias might be various from zero. If programming raters tend programmers disagree, but with out computer technology constant sample of one rating higher than programming other, programming mean will be near zero. Confidence limits usually 95% can be calculated for both programming bias and every of programming limits of contract. There are a few formulae that can be used programmers calculate limits of contract. The simple formulation, which was given in programming old paragraph and works well for sample size greater than 60, isBland and Altman have extended on this idea by graphing programming change of each point, programming mean change, and programming limits of contract on programming vertical against programming common of programming two scores on programming horizontal. The resulting BlandAltman plot demonstrates not only programming ordinary degree of agreement, but also no matter if programming contract is associated programmers programming underlying value of programming item.
