Formulas in AWF-Wiki are created with the Tex markup language. Everyone who used LaTeX before is familiar with this. For those users that do not have any experiences with TeX it might be hard work for the first formula! Nevertheless it is defenetly worth the trouble, because the outcome is perfect. If you once formated formulas in TeX, you can also import them in many other applications.
Unfortunately it is defenetly not possible to write down a formula without any knowledge about TeX. The following example shows a medium complex estimator for the variance of a stratified sample:
\[\hat {var} (\bar y) = \sum_{h=1}^L \left\lbrace \left( \frac {N_h}{N} \right)^2 \hat {var} (\bar y_h) \right\rbrace = \frac{1}{N^2} \sum_{h=1}^L N^2_h \frac {N_h-n_h}{N_h} \frac {S^2_h}{n_h}\]
This formula is the outcome of the following syntax:
:<math>\hat {var} (\bar y) = \sum_{h=1}^L \left\lbrace \left( \frac {N_h}{N} \right)^2 \hat {var} (\bar y_h) \right\rbrace = \frac{1}{N^2} \sum_{h=1}^L N^2_h \frac {N_h-n_h}{N_h} \frac {S^2_h}{n_h}</math>
The above estimator is not complicate, we have much more complex expressions in (Forest)science and you can imagine that it takes time to get familiar with this kind of markup. In case that you want to contribute to AWF-Wiki but you are afraid of this, let us know and we can help!
