Description: 3D Transforms Demonstration Program. Requires Turbo C Version 1.5.
Project file should contain the line
DEMO3D.C GRAPHICS.LIB 3D.LIB DRIVERS.LIB
The library directory must include 3D.LIB and GRAPHICS.LIB, and the
include directory must include 3D.H. DRIVERS.LIB must be created by
converting the .BGI files to .OBJ files (using the BGIOBJ utility in
Turbo C version 1.5) and collecting them in a library (using TLIB).
The program displays a cube, a tetrahedron, and an octahedron in
three dimensions. Each figure is rotated about a different axis. Platform: |

Description: PRINCIPLE: The UVE algorithm detects and eliminates from a PLS model (including from 1 to A components) those variables that do not carry any relevant information to model Y. The criterion used to trace the un-informative variables is the reliability of the regression coefficients: c_j=mean(b_j)/std(b_j), obtained by jackknifing. The cutoff level, below which c_j is considered to be too small, indicating that the variable j should be removed, is estimated using a matrix of random variables.The predictive power of PLS models built on the retained variables only is evaluated over all 1-a dimensions =(yielding RMSECVnew).

Description: 计盒分形维数计算的matlab源代码编程实现过程-Function [Fdgen NoisfreFD ]=fractaldim(y,Q,M)
__________________________________________________________________________
Usage: Computes fractal dimension by box counting(BC) method.
NOTE: Running the code may take a little time, because it calculates
dimensions for all embedding dimensions up to M.
This code is based on an algorithm that constructs a box for the first
observation and for other observations test which it belongs to previous
box(s). If the observation belongs to one of the existent boxes then
increases number of points in the relevant box,otherwise makes a new box. the algorithm of this code uses only rounding down and it does not need
binary coding, sorting and so on. It uses only transformation data to [0,2^32-1] and finding valid boxes based on Leibovich and Toth(1989). Inputs: y is a vector time series. q stands for generalized dimension q=1 entropy dimension,q=2 correlation dimension and so on. q=0 is box counting dimen Platform: |
