Interlaboratory Studies (ILS)

ILS
Interlaboratoty Study

Univariate Data Analysis

The ILS package .

lab.qcdata()
Quality Control Data
lab.qcs() print(<lab.qcs>) summary(<lab.qcs>)
Create an object of class 'lab.qcs' to perform statistical quality control. This function is used to compute statistics required for plotting Statitics
h.qcs()
Function to estimate the univariate Mandel's h statistic
k.qcs()
Function to calcute the Mandel's k statistic
cochran.test()
Function to compute the Cochran test statistic
grubbs.test()
Function to compute the Grubbs test statistic
lab.aov()
Function to compute the AOV
plot(<lab.qcdata>)
Plot method for 'lab.qcdata' objects
plot(<lab.qcs>)
Plot method for 'lab.qcs' objects

Functional Data Analysis (FDA)

FDA

ils.fqcdata()
Functional Quality Control Data
ils.fqcs() print(<ils.fqcs>) summary(<ils.fqcs>)
It developes an object of class 'ils.fqcs'
mandel.fqcs()
This function is used to compute the FDA Mandel's h and k statistic
outliers.ils()
Detecting outliers for functional dataset
boot.sim.set()
Bootstrap samples of a functional statistic
func.ils.formula()
Descriptive measures for functional data.
plot(<ils.fqcdata>)
Plotting method for 'ils.fqcdata' objects
plot(<ils.fqcs>)
Plotting method for 'ils.fqcs' objects
plot(<mandel.fqcs>)
Plotting method for 'mandel.fqcs' objects

Databases used in the package

In order to carry out interlaboratory studies, two studies have been carried out with both univariate data and functional data, obtaining the following databases.

Clinical study of blood glucose measurement.

Glucose
Glucose in Serum

Characterization of materials by thermogravimetric analysis.

TG
Thermogravimetry curves
DSC
Differential Scanning Calorimetry curves
IDT
Dataset composed of the initial decomposition temperature (IDT) of different samples of Calcium Oxalate, obtained by 7 different laboratories
