The Brownian motion component of the model can be replaced with fractional Brownian motion with parameter \(0
In the fractional Brownian model with \(v
For 1000 equally spaced \(t\)-values in \((0,10]\) compute the FBM covariance matrix \(K\) and its Choleski factorization \(K=L^{\prime} L\). (If \(t=0\) is included, \(K\) is rank deficient, and the factorization may fail.) Thence compute \(Y=L^{\prime} Z\), where the components of \(Z\) are
Several plants reach their plateau well before the end of the observation period. How is the analysis affected if repeated values are removed from the end of each series?
Explain the purpose and the implementation of the Box-Tidwell method. Why must the unmodified REML criterion be avoided?
Investigate the relation between brearding date and ultimate plant height. Is it the case that early-sprouting plants tend to be taller than late-sprouting plants?
