In this paper we obtain parameter estimators based on length (size) biased samples for different models. We compare the estimators and Fisher's information from usual samples and length biased samples. Moreover, we obtain the estimators based on two samples, one unbiased and another one biased. We obtain a similar study for samples from a renewal process.
