comment Frequency of letters change by the length of the texts?
There are two different effects: 1) For short texts the frequency won't be statistically significant unless you average over many independent samples 2) Different kinds of text use different words. For example the word frequencies you'd get from emails would be very different from those on wikipedia. It's very well possible that this shifts the frequency of letters somewhat.
