CPT Help Home -> Acknowledgements AcknowledgementsCPT was developed using version 3.5.0 of LAPACK for the singular value decomposition used in the CCA, PCR, and MLR algorithms, including in the missing value estimation using multiple nearest neighbours. Algorithm AS 27 by G. A. R. Taylor (1970) Applied Statistics, 19(1), 113-114, is used to calculate upper-tail areas under the Student's t-distribution; Algorithm AS 91 by D. J. Best and D. E. Roberts (1975) Applied Statistics, 24(3), 385-388, and Algorithm AS R85 by B. L. Shea (1991) Applied Statistics, 40(1), 233-235, are used to calculate the deviate corresponding to a given lower-tail area of the chi-squared distribution; Algorithm AS 239 by B. L. Shea (1988) Applied Statistics, 37(3), 466-473, is used to calculate the lower-tail area corresponding to a gamma deviate; Algorithm AS 241 by M. J. Wichura (1988) Applied Statistics, 37(3), 477-484, is used to calculate the deviate corresponding to a given lower tail area of the normal distribution. Algorithm ACM 396 by G. W. Hill (1970) Communications of the ACM (Association for Computing Machinery), 13(10), 617-619, is used to calculate positive quantiles of the Student's t-distribution. Approximate values for the error function are calculated using Rational Chebyshev approximations for the error function by W. J. Cody (1969) Mathematics of Computation, 23, 631-638. The procedure for estimating the gamma distribution parameters is derived from A note on the gamma distribution by H. C. S. Thom (1958) Monthly Weather Review, 86, 117-122.The country borders, coastlines, lakes and inland seas are extracted from the Environmental Systems Research Institute (ESRI) ArcWorld dataset. Substantial input on the design of the software was provided by Glenroy Brown, Andrew Colman, Igor Khomayakov, Theodore Marguerite, Ousmane Ndiaye, and Cédric van Meerbeeck. Translations were provided by Walter Baethgen, Jean-Pierre Céron, Katia Fernandes, Luis Alfonso López, Gilma Mantilla, Ángel Muñoz, Juan-Jose Nieto, Cristina Recalde, and Reinaldo Silveira. Assistance with the construction of the URLs for the data downloads from the IRI Data Library was provided by Michael Bell. These Help Pages were written with the assistance of Ashley Curtis and Amy Lafferty.
Work to develop the CPT has been supported financially in part by the National Oceanic and Atmospheric Administration (NOAA),
the United States Agency for International Development (USAID), and the National Research Foundation of South Africa.
