Finally, on the basis of results of marker number and training population size, we completed 100 iterations for combinations of marker number and training. For comparisons, if groups had nonoverlapping correlation 95 confidence intervals, we considered them statistically significant. As a technical note, the 1 indicates that an intercept is to be. ASREML-R (Butler, 2009) was used to fit the mixed model. Notice the grammar in the lme function that defines the model: the option random1Individual is added to the model to indicate that Individual is the random term.

Another way to construct a mixed effects model for interval/ratio data is with the lme function in the nlme package.

Gaylor DW, Hopper FN (1969) Estimating the degrees of freedom for linear combinations of mean squares by Satterthwake's formula. H is a function of F′, therefore, we used F′ to define an approximate (1− α) interval estimator for H. Using predict() across multiple models to generate confidence intervals in R My goal is to create multiple models from a dataframe and then generate confidence intervals around the fitted values that correspond to those different models. It was shown that F′=/ has an approximate F-distribution with df″ and df′ degrees of freedom, respectively, where M′ and M″ are mean squares corresponding to E(M′) and E(M″), respectively. H reduced to a function of constants and a single expected mean square ratio in every case H=1−E(M′)/E(M″) where E(M′) is a linear function of expected mean squares and E(M″) is a single expected mean square. Our objective was to derive H interval estimators for these cases. Previously described H interval estimators do not apply to onefactor mating designs in split-plot in time experiment designs in one or more locations, one-factor mating designs for several experiment designs in two or more locations and years, and two-factor mating designs for several experiment designs in two or more locations or years. Confidence interval estimators have not been described for several heritability (H) estimators relevant to recurrent family selection. of 0.15 which also had a very wide confidence interval of -0.38 to 0.61.
