+
+Erlang statistics module. The current stdlib in OTP is lacking a statistics module.
+I hope to add one sooner or later, in the meanwhile I will add stuff here.
+
+In other words: the API will be subject to change until I feel it could be fixated.
+
+Currently we have:
+
+* `mean/1 -> Mean :: float()` - calculate the mean of list of numbers,
+* `msn/1 -> {Mean :: float(), StdDev :: float()}` - calculate mean and *sampled* standard deviation,
+* operations
+
+Todo:
+
+* histogram
+* distributions
+* anything useful for testing
