Logarithmic Error Propagation


So reviewers "should" be looking for confidence intervals in general and not standard error based bars. Apply Today MATLAB Academy New to MATLAB? So while the SD of the raw data can be added to, or subtracted from, the arithmetic mean, thegeometric SDmust be multiplied times, or divided into, the geometric mean. These settings are on the Format Axis dialog.

In large enough samples, then the average of log X will be normally distributed with mean log(mu) and variance 1. I tried lerrorplot = errorplot /. {x_Real, y_Real} -> {[email protected], [email protected]} but I just got a green box. –s0rce Apr 4 '12 at 19:25 add a comment| up vote 2 down Learn MATLAB today!

This makes sense as the lognormal distribution is asymmetrical. Standard Error Of Log Transformed Data Messages are exchanged and managed using open-standard protocols. Further, in an exponential distribution 1 sd will encompass the vast majority of the data points, while in a Gaussian distribution it will only encompass 68%.

The two parameters of the Gamma, the shape and the scale, can be estimated and plotted on the Gamma (shape, scale)-plane with 95% confidence intervals for each.
