Problem 1: Sire Model
As already shown during the lecture for the small data set at
https://charlotte-ngs.github.io/lbgfs2024/data/small_beef_data.csv
a sire model is to be used for the following dataset, already used in Exercise 4. The data set is available from
https://charlotte-ngs.github.io/lbgfs2024/data/beef_data_bc.csv
The ration between the residual variance and the sire variance can be assumed to be
Solution
_webr_editor_1 = Object {code: null, options: Object, indicator: Ke}
_webr_editor_2 = Object {code: null, options: Object, indicator: Ke}
_webr_editor_3 = Object {code: null, options: Object, indicator: Ke}
- Coefficient matrix of mixed model equations
_webr_editor_4 = Object {code: null, options: Object, indicator: Ke}
- Right-hand side of mixed model equations
_webr_editor_5 = Object {code: null, options: Object, indicator: Ke}
- Solve mixed model equations
_webr_editor_6 = Object {code: null, options: Object, indicator: Ke}
- Identify estimates of fixed effects and predictions of sire effects
_webr_editor_7 = Object {code: null, options: Object, indicator: Ke}
