Sentence examples for linear hypothesis from inspiring English sources

The linear hypothesis had its origin in 1927, when the geneticist Dr. H. J. Muller published a paper on his work eliciting gene mutations in fruit flies by bombarding them with radiation from X-rays.

Some exact tests for testing linear hypothesis are proposed for the models.

Furthermore, a linear hypothesis method is proposed to fill up the gaps in the trajectories.
