IDT
(Package: ILS) :
Dataset composed of the initial decomposition temperature (IDT) of different samples of Calcium Oxalate, obtained by 7 different laboratories
Initial decomposition temperature (IDT) is a parameter defined by temperature at which a material loss 5% of its weight when it is heated using a constant rate. One hundred and five calcium oxalate samples were tested by thermogravimetric analysis (TG), obtaining 105 TG curves from which the IDT is extracted. Summarizing, IDT dataset is composed of the IDT values of calcium oxalate obtained by 7 different laboratories that analyze 15 oxalate samples each one.: Laboratory 1 uses a simultaneous thermal analyzer (STA) with an old calibration program, Laboratory 2 to Laboratory 4 use a SDT simultaneous analyzer, Laboratory 6 utilizes a SDT simultaneous analyzer with an old calibration, and Laboratory 7 uses a SDT simultaneous analyzer with a biased calibration (2 degrees Celsius shifted from the zinc melting point).

bootstrap.quantile
(Package: ILS) :
Compute functional (FDA) Mandel's h and k statistics
This function is used to compute functional (FDA)Mandel's h and k, statistics, required to perform Interlaboratory studies, and to detect non-consistent laboratories where data show a functional form (curve). In addition, bootstrap resampling methodology is used to estimate functional distributions. This allow to perform bootstrap confidence bands for FDA h and k statistics.
