this package contain: five matlab function and one script. XOX_OLS: is Common ols regression function that print out results just like Eviews Program. XOX_PanelFix: is Common fix effect panel data regression function that print out results just like Eviews. XOX_PanelRandom: is Common random effect panel data regression function that print out results just like Eviews. XOX_print: is the function for print an matrix in formatted form for panel data results. XOX_FuzzyRegression: is a fuzzy linear regression model function that based on triangle membership function. XOX_ANFIS: is an escript to explain prediction using TAKAGI-SUGENU adaptive neural based inference system.

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.
