Growth Curve Models with Linear Structure for Location and Variance Parameters.

Consistent Variance Curve Models

We introduce equity forward variance term-structure models and derive the respective HJM-type arbitrage conditions. We then discuss finitedimensional Markovian representations of the infinite-dimensional fixed time-to-maturity forward variance swap curve and analyse examples of such variance curve functionals. The results are then applied to show that the speed of mean-reversion in standard sto...

Estimation of (co) variance components and genetic parameters for growth traits in Arman sheep

(Co) variance components and genetic parameters for growth traits in Arman sheep were estimated, using data collected during an 11-year period (1999-2010), by applying the restricted maximum likelihood (REML) procedure under univariate and bivariate animal models. The studied traits were body weight of lamb at birth (BW), body weight at 3 months of age as weaning weight (WW), body weight at 6 m...

Latent Growth Curve Models

(Co)variance components and genetic parameters for growth traits in Arabi sheep using different animal models.

The objective of the present study was to estimate genetic parameters for body weight at different ages in Arabi sheep using data collected from 1999 to 2009. Investigated traits consisted of birth weight (N = 2776), weaning weight (N = 2002) and weight at six months of age (N = 1885). The data were analyzed using restricted maximum likelihood analysis, by fitting univariate and multivaria...

For example, in a recent partially ra...
