When a problem is ill posed it is difficult to get what it is really asked for.
Suppose I generate data from a NORMAL MODEL N(mu, var). Considering any finite set N of values we know that, generally speaking, the sample mean, m, does not coincide with mu.
_______ mu = m + bias
This bias tends to ZERO when N grows ro infinity.
The same way in what concerns variance and its unbiased estimator, the sample variance, svar, which?s the sum of the squared deviations divided by N-1.
________ svar = var + bias´
