...experimental distributions. I use nls() to the fit the 2 distribution and it works pretty well. The statistical comparison of 2 non linear fits is well described in the book "Fitting Models to Biological Data using Linear and Nonlinear Regression" from Harvey Motulsky and Arthur Christopoulos. This test is based on the calculation of an F-value that compares the residuals of 1°) the global fit of both data sets (with one value for each parameter) on one hand, 2°) with the 2 fits of each separate data sets (with thus 2 values for each parameter) on the other hand. This methods allo...

Hi, After a quick read of the Theora spec, I became curious about the possibility of fast quality reduction of Theora videos. The idea is to decode through the Huffman and reverse prediction steps, and then to truncate the coefficients and reencode. My questions are: * Is this a reasonable way to reduce the quality and bitrate of a stream? Will it be comparable in quality to a complete
