| Abstract: |
| Based on the definition of the frequency interpolation, which is more reasonable and converge faster than histogram estimation, a single variable frequency interpolation function is proved to be the consistent and asymptotic unbiased estimator. |
| Key words: density estimation frequency interpolation histogram asymptotic unbiase consistency |
