Confidence intervals computed using pairwise Wilcoxon rank sum tests applied to 50 resamplings of 13 data sets. Abbreviations: ACOMP, closed proportions; CLR, centered log ratio-transformed data; PBA, principal balances; ABA, anti-principal balances; RBA, random balances; DBA, discriminative balances...
there is no one-to-one relation between the original mean and the mean of the log-transformed data...it is not conceptually sensible to compare the variability of the data with its transformed counterpart ... comparing the means of two samples is not the same as com...
Without identifying specific bar patrons, it posts information like the average age of a crowd and the ratio of men to women, helping bar-hoppers decide where to go. More than 50 bars in Chicago participate. As SceneTap suggests, techniques like facial detection, which perceives human faces ...

Since the dawn of photography and video the only way to really change the signal to noise ratio and ultimately how noisy the pictures are is by changing how much light you put onto the sensor. Gain, gamma, log, raw, etc etc only have a minimal effect on the signal to noise ratio. Mo...
For a comparison of two independent groups, the relative treatment effect is the ratio of group geometric means (or alternatively, group arithmetic means) and the coefficient of variation is used as a summary of relative variability. For a matched-pairs comparison, the appropriate relative treatment...
Linear model with log-transformed response vs. generalized linear model with log link In the following I try to give some additional details to @Meg's answer with some mathematical notation. The fixed part is the same for both, transformation and GLM. However, the transformation also ... ...
The width/height ratio for WebGL Canvases are now automatically determined. The corresponding visual specification will now act as an override if set. Added a tap event to Canvases, Canvas.tap(). This event is a mobile event, and is fired when a user presses down and releases within a ...
