Testing the Morphological Aspects of Polyethylene Glycol-primed Tomato Seeds with Proportional Odds Analysis

Ordinal regression modelling between proportional odds and non-proportional odds

Enhanced Expression of BiP Is Associated with Treatments that Extend Storage Longevity of Primed Tomato Seeds

While seed priming (hydration in water or osmotic solutions followed by drying) enhances seed germination performance, the longevity of primed seeds in storage often is reduced. Postpriming treatments including a reduction in seed water content followed by incubation at 37 or 40 °C for 2 to 4 h can substantially restore potential longevity in tomato (Lycopersicon esculentum Mill.) seeds. These ...

the impact of morphological awareness on the vocabulary development of the iranian efl students

this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...

Analysis of cure rate survival data under proportional odds model.

Due to significant progress in cancer treatments and management in survival studies involving time to relapse (or death), we often need survival models with cured fraction to account for the subjects enjoying prolonged survival. Our article presents a new proportional odds survival models with a cured fraction using a special hierarchical structure of the latent factors activating cure. This ne...

Computing estimates in the proportional odds model

In this paper we present an algorithm for maximum likelihood estimation in the proportional odds model. The algorithm is an example of optimization transfer, also known as the method of iterative majorization. We discuss optimization transfer, present the proportional odds algorithm, and give a means for accelerating the convergence of the algorithm. The algorithm is stable and guaranteed to co...
