His Econometrics research is multidisciplinary, incorporating perspectives in Test, Analysis of variance and Biometrics.
His study looks at the relationship between Sampling design and fields such as Sample, as well as how they intersect with chemical problems.
His most cited work include:
- Biometrika Tables for Statisticians (1298 citations)
- Maximum Likelihood Estimation from Incomplete Data (533 citations)
- Maximum-likelihood estimation for the mixed analysis of variance model (482 citations)
What are the main themes of his work throughout his whole career to date?
H. O. Hartley focuses on Statistics, Section, Econometrics, Estimator and Applied mathematics.
He performs integrative study on Statistics and Estimation in his works.
His work on Bias of an estimator, U-statistic and Efficient estimator as part of general Estimator study is frequently connected to MINQUE, therefore bridging the gap between diverse disciplines of science and establishing a new relationship between them.
His Applied mathematics research is multidisciplinary, relying on both Mathematical optimization and Total least squares, Least squares, Generalized least squares, Non-linear least squares.
Mathematical model is closely connected to Stochastic process in his research, which is encompassed under the umbrella topic of Mathematical optimization.
His work carried out in the field of Sample brings together such families of science as Goodness of fit and Confidence interval.
