چکیده
It is worth keeping in mind the trade-off: Bayes estimators although easy to compute are somewhat subjective (in that they depend strongly on the prior π). Minimax estimators although more challenging to compute are not subjective, but do have the drawback that they are protecting against the worst-case which might lead to pessimistic conclusions, i.e. the minimax risk might be much higher than the Bayes risk for a “nice” prior.

The other way to avoid the curse of dimensionality is to assume sparsity, this means that even though we have many covariates, the true regression function only (strongly) depends on a small number of relevant covariates. This is the type of setting we will focus on. More broadly, the main idea is that we want to think about practically relevant structural properties (like smoothness/sparsity) ...

Problem 1[C&B] 5.39 b. Using the normal approximation, we have µ v = r(1 − p)/p = 20(.3)/.7 = 8.57 and σ v = ï¿¿ r(1 − p)/p 2 = ï¿¿ (20)(.3)/.49 = 3.5.
متن کاملInhibition of cholesteryl ester transfer protein activity by JTT-705 increases apolipoprotein E-containing high-density lipoprotein and favorably affects the function and enzyme composition of high-density lipoprotein in rabbits.
BACKGROUND Inhibition of cholesteryl ester transfer protein (CETP) is an efficient way to increase high-density lipoprotein (HDL) levels in humans. We investigated the effects of the inhibition of CETP activity by a CETP inhibitor, JTT-705, on the function and composition of HDL particles. METHODS AND RESULTS Japanese white rabbits were fed either normal rabbit chow LRC-4 (n=10) or a food adm...
متن کاملT-705 (favipiravir) inhibition of arenavirus replication in cell culture.
A number of New World arenaviruses (Junín [JUNV], Machupo [MACV], and Guanarito [GTOV] viruses) can cause human disease ranging from mild febrile illness to a severe and often fatal hemorrhagic fever syndrome. These highly pathogenic viruses and the Old World Lassa fever virus pose a significant threat to public health and national security. The only licensed antiviral agent with activity again...
متن کاملComparative Multibody Dynamics Analysis of Falls from Playground Climbing Frames
This paper shows the utility of multibody dynamics in evaluating changes in injury related parameters of the head and lower limbs of children following falls from playground climbing frames. A particular fall case was used as a starting point to analyze the influence of surface properties, posture of the body at impact, and intermediate collisions against the climbing frame before impacting the...
