Optimized Variance-Stabilizing Transformations - released 1 July 2009 ------------------------------------------------------------------------------------------------------------ (c) 2008-2009 Alessandro Foi Tampere University of Technology, Tampere, FINLAND http://www.cs.tut.fi/~foi/optvst firstname.lastname@tut.fi ------------------------------------------------------------------------------------------------------------ This package includes the optimized variance-stabilizing transformations illustrated in the paper Foi, A., "Optimization of variance-stabilizing transformations", submitted, 2009. The transformations are represented by the two vectors z and f, where f corresponds to f(z). They are stored in both Matlab MAT (.mat) and ASCII (.txt) format. Type of optimization RecInt .......... Recursive integral DSmono .......... Direct search monotone DSnonM .......... Direct search nonmonotone Distribution family Bin ............. Binomial (number of trials specified at the end of the filename) NegBin .......... Negative binomial (exponent specified at the end of the filename) Poisson ......... Poisson FiltPoisson ..... Filtered Poisson by 5x5 2-D B_3-spline filter SplicePoisson ... Spliced transformation (optimized direct search monotone + Anscombe) ClipHetNorm ..... Clipped heteroskedastic normal a=1/30 b=0.01 [ here the two vectors are ztilde and f = f(ztilde) ] CostFun ......... Cost functional (A, B, or C) Matlab MAT-file (ver. 5 or later) 16-digit ASCII (double precision) ================================= ================================= VST_Bin_DSmono__4.mat VST_Bin_DSmono__4.txt VST_Bin_DSmono__7.mat VST_Bin_DSmono__7.txt VST_Bin_DSmono__12.mat VST_Bin_DSmono__12.txt VST_Bin_DSmono__15.mat VST_Bin_DSmono__15.txt VST_Bin_DSmono__30.mat VST_Bin_DSmono__30.txt VST_Bin_DSnonM__4.mat VST_Bin_DSnonM__4.txt VST_Bin_DSnonM__7.mat VST_Bin_DSnonM__7.txt VST_Bin_DSnonM__12.mat VST_Bin_DSnonM__12.txt VST_Bin_DSnonM__15.mat VST_Bin_DSnonM__15.txt VST_Bin_DSnonM__30.mat VST_Bin_DSnonM__30.txt VST_Bin_RecInt__4.mat VST_Bin_RecInt__4.txt VST_Bin_RecInt__7.mat VST_Bin_RecInt__7.txt VST_Bin_RecInt__12.mat VST_Bin_RecInt__12.txt VST_Bin_RecInt__15.mat VST_Bin_RecInt__15.txt VST_Bin_RecInt__30.mat VST_Bin_RecInt__30.txt VST_ClipHetNorm_DSmono.mat VST_ClipHetNorm_DSmono.txt VST_ClipHetNorm_RecInt.mat VST_ClipHetNorm_RecInt.txt VST_FiltPoisson_DSmono.mat VST_FiltPoisson_DSmono.txt VST_NegBin_DSmono__2.mat VST_NegBin_DSmono__2.txt VST_NegBin_DSmono__5.mat VST_NegBin_DSmono__5.txt VST_NegBin_DSmono__10.mat VST_NegBin_DSmono__10.txt VST_NegBin_DSnonM__2.mat VST_NegBin_DSnonM__2.txt VST_NegBin_DSnonM__5.mat VST_NegBin_DSnonM__5.txt VST_NegBin_DSnonM__10.mat VST_NegBin_DSnonM__10.txt VST_NegBin_RecInt__2.mat VST_NegBin_RecInt__2.txt VST_NegBin_RecInt__5.mat VST_NegBin_RecInt__5.txt VST_NegBin_RecInt__10.mat VST_NegBin_RecInt__10.txt VST_Poisson_CostFun_A_DSmono.mat VST_Poisson_CostFun_A_DSmono.txt VST_Poisson_CostFun_A_DSnonM.mat VST_Poisson_CostFun_A_DSnonM.txt VST_Poisson_CostFun_A_RecInt.mat VST_Poisson_CostFun_A_RecInt.txt VST_Poisson_CostFun_B_DSmono.mat VST_Poisson_CostFun_B_DSmono.txt VST_Poisson_CostFun_B_DSnonM.mat VST_Poisson_CostFun_B_DSnonM.txt VST_Poisson_CostFun_B_RecInt.mat VST_Poisson_CostFun_B_RecInt.txt VST_Poisson_CostFun_C_DSmono.mat VST_Poisson_CostFun_C_DSmono.txt VST_Poisson_CostFun_C_DSnonM.mat VST_Poisson_CostFun_C_DSnonM.txt VST_Poisson_CostFun_C_RecInt.mat VST_Poisson_CostFun_C_RecInt.txt VST_SplicePoisson.mat VST_SplicePoisson.txt Disclaimer: Any unauthorized use of these routines for industrial or profit-oriented activities is expressively prohibited.
