Randomized trial shows improved species estimation in ecological sampling, suggesting better prediction methods.

This study aims to estimate the number of species and develop a prediction function for future sampling.
Introduced a new estimator for species prediction based on essential properties.
Compared the new estimator with the Efron and Thisted method.
Illustrated the estimator using two numerical examples and a simulation study.
The proposed estimator retains essential properties of the true prediction function.
Demonstrated enhanced accuracy for large values of the sample size parameter t.
Simulations showed that the new estimator outperforms existing methods.

Boneh et al. (1998) studied this question.
