In this note, we briefly describe some biased regresion methods : principal component regression, latent root regression analysis, partial least square regression, ridge regression and use of James-Stein's estimators. All these methods are illustrated by an example. [less ▲]

Comparative assessment of right ventricular performance from the pressure-volume relationship in double-muscled and conventional calves.

in Canadian Journal of Veterinary Research = Revue Canadienne de Recherche Vétérinaire (1995), 59(2), 135-141

Forty-one and 55 records of right-sided and systemic arterial pressures, cardiac output, and end-diastolic and end-systolic right ventricular volumes were collected from a group of 6 conventional and 6 double-muscled calves, respectively. In each group, the mean right ventricular pressure-volume loop was constructed. Global cardiac performance was significantly lower in the double-muscled than in the conventional calves. The right ventricular end-diastolic and end-systolic volumes, as well as the diastolic portion of the mean pressure-volume loop, were similar in the 2 groups. Those results suggest that the reduced cardiac performance of double-muscled calves is not due to a lowered ventricular preload and that diastolic properties of their myocardium are similar to those of conventional calves. When expressed on a body weight basis, however, the right ventricular end-diastolic and end-systolic volumes were lower in the double-muscled than in conventional calves. When expressed as a function of probable metabolic demand, therefore, the volumetric capacity of the cardiac pump appears to be reduced in double-muscled calves. The significantly lower right ventricular ejection fraction, maximal rate of ventricular pressure rise and right ventricular peak-systolic pressure to end-systolic volume ratio measured in double-muscled as compared with conventional calves suggest that reduced myocardial contractility may also be partly responsible for the significantly lower stroke index of the former calves. The cardiac pump of double-muscled cattle thus seems to be less effective than that of conventional cattle because of reduced volumetric capacity and lowered strength of contraction. [less ▲]

This paper outlines the first permanent inventory carried out since the beginning of 1994 for monitoring and updating the forest resources in the Walloon region of Belgium (covering about 530.000 hectares of forests). The so-called inventory is based upon a systematic sampling design which takes into account 1 plot to 50 ha (grid of 0,5 x 1 km). The main objectives are : to continuously monitor the changing situation of forest resources and focus attention on the wooded production, availability and probable trends in the future, to assist the formulation of the medium and the long-term development plan of the forestry sector, to provide information for long-term planning, control and improve general forest management programs. Methodological aspects are given concerning the survey design, the sampling units and the collection of data. The processing of data, the type and the presentation of expencted results are also briefly descriebed. Some recommandations concern the way which could be used in terms of organizational structure and logistical support. [less ▲]
