Under a local dependence assumption about the p-values, an estimator of the proportion TTQ of true null hypotheses, having a closed-form expression, is derived based on Bernstein polynomial density estimation. A nonparametric estimator of false discovery rate (FDR) is then obtained. These estimators are proved to be consistent, asymptotically unbiased, and normal. Confidence intervals for π0 and the FDR are also given. The usefulness of the proposed method is demonstrated through simulations and its application to a microarray dataset.
