1. Restrições da correlação nos testes de germinação de sementes e emergência de plântulas / Restrictions of the correlation in the tests of seed germination and seedling emergence
Coefficient of Pearson r is used to compare scientific tests. In seeds technology it is used to compare results of procedures that measure vigour. When the correspondly similar results are not found in very similar conditions, Persons correlation faces criticism mainly due to two factors. The first one comes from statistics for whose usage of Persons correla

3. The Genetic Analysis of Quantitative Trait Differences between Two Homozygous Lines
Previous maximum likelihood methods to analyze quantitative data on two inbred parental strains, their F1 and backcross generations are extended in three directions: (1) a method is suggested to transform the data to better satisfy the assumptions of normality and homoscedasticity; (2) the likelihoods are modified to allow for litter correlations and heteros
