OVERVIEW OF LEAST-SQUARES, MAXIMUM LIKELIHOOD AND BLUP PART 2
2
LIKELIHOOD-BASED INFERENCE
3
1. The likelihood function
6
3. Information (Fisher’s) contained in the likelihood
9
5. Asymptotic Properties of Maximum Likelihood Estimators
25
BEST LINEAR UNBIASED ESTIMATION AND BEST LINEAR UNBIASED PREDICTION
29
C. Alternative method for computing BLUE (GLS) estimator of the vector of fixed effects: known V
36
EXAMPLE: BLUP OF 599 WHEAT LINES
40
IS BLUP OVERFITTING. FITCOR<-cbind(y,MATPAIR) cor(FITCOR) Y. BLUPR
IS BLUP OVERFITTING? FITCOR<-cbind(y,MATPAIR) cor(FITCOR) Y BLUPR BLUP1 BLUP2 BLUP3 BLUP4 BLUP NO EVIDENCE BUT BLUPS CLOSELY CORRELATED
41
####HOW ABOUT TRAINING MEAN-SQUARED ERROR
####HOW ABOUT TRAINING MEAN-SQUARED ERROR? mse<-numeric(6) for (i in 1:6){ mse[i]<-sum((y-MATPAIR[,i])**2)/n } mse [1]
