Estimate measurement results including confidence intervals

- - -

Description

- -

-This function generates estimates for x values from y values, including -a confidence interval for the x values. The formulas in this function used -for prediction of concentrations from (replicate) measurements are taken from -the "Handbook of Chemometrics and Qualimetrics Part A" by D. L. Massart, -Vandeginste, B. G. M., Buydens, L. M. C., De Jong, S., Lewi, P. J. and -Smeyers-Verbeke, J, Elsevier, Amsterdam, 1997 and from the EURACHEM/CITAC -report on "Quantifying uncertainty in analytical measurement", 2000, -pp. 111f. -

Usage

- -
-  calpredict(yobs,xi,yi,xunit="",level=0.95,intercept=FALSE,syobs=FALSE)
-
- - -

Arguments

- - - - - - - - - - - - - - - - -
yobs -A numeric vector containing the observed data. -
xi -A vector of x values of the calibration. -
yi -A vector of y values of the calibration. -
xunit -The unit of the given values on the x axis as a character string. -
level -The desired confidence level for the confidence interval of the -estimates. Defaults to 0.95. -
intercept -Logical value determining if an intercept is to be fitted or not. -Default is FALSE. -
syobs -If TRUE, a standard deviation for the given y values is -calculated, and the resulting confidence interval will -include this variability (not validated yet). If FALSE (default), this -standard deviation is not included in the -confidence interval. If a numeric value is given, -it is used for the standard deviation of "real samples", -in addition to the standard deviation of the y values -in the calibration (also not validated yet). -
- -

Value

- -

-A list containing the estimate, its standard deviation and its -confidence interval.
