A procedure for lowering the mean square error (MSE) of minimum variance unbiased linear estimator (MVULE) a population is considered. The technique employed shrinkage MVULE towards natural origin, μ0, in parameter space. suggested is: case where μ0 = 0 given special consideration. This general normal distribution. When |μ/σz| small, buys decreased MSE at expense increased large.
Tne maximum likelihood estimate of a probability density function based on random sample does not exist in the nonparametric case. For this reason and others heuristic Bayesian considerations Good Gaskins suggested adding penalty term to likelihood. They proposed two terms; however they did establish existence or uniqueness their penalized estimates. also an alternate approach for calculating which avoids nonnegativity constraint estimate. In present work both Good's Gaskins' estimates are...
Abstract Background We sought to identify features that distinguish osteoarthritis (OA) and rheumatoid arthritis (RA) hematoxylin eosin (H&E)-stained synovial tissue samples. Methods compared fourteen pathologist-scored histology computer vision-quantified cell density (147 OA 60 RA patients) in H&E-stained samples from total knee replacement (TKR) explants. A random forest model was trained using disease state (OA vs RA) as a classifier and/or inputs. Results Synovium patients had...
An attempt is made to model the appearance times of metastases as a nonstationary Poisson process. Three algorithms are developed for this task. The first follows kernel approach used in probability density estimation by Parzen and Rosenblatt; second extends work Grenander on mortality measurements more general censoring scheme appropriate present application; third employs discrete maximum penalized likelihood approach. We obtain estimates using both stratification proportional hazards...
A nonparametric probability density estimator is proposed that optimal with respect to a discretized form of continuous penalized-likelihood criterion functional. Approximation results relating the discrete estimate obtained by solving corresponding infinite-dimensional problem are presented. The shown be consistent. numerical implementation this outlined and examples displayed. simulation study compares integrated mean square error well-known kernel estimators. Asymptotic rates convergence...
Methods are presented for estimating the growth curve of a tumor (up to an unknown scale factor time) from distribution volumes at detection on basis two assumptions: 1) existence common and 2) assumption that probability detecting in period time is proportional volume. These methods can accommodate variation between individuals speed traversal curve. The applied large series breast cancers. simplest, adequate description exponential with great individual-to-individual doubling time. data...

A single-sample procedure is given for selecting the least probable event in a multinomial distribution. Given two numbers $(c, P^\ast)$, it required to determine smallest sample size which probability of correct selection at as large $P^\ast$ when (unknown) difference between and next cell probabilities greater than or equal $c$. table showing specified values $c$ $P^\ast$.

As a result of the COVID-worldwide pandemic, United States instituted various non-pharmaceutical interventions (NPIs) in an e ort to slow spread disease.Although necessary for public safety, these NPIs can also have deleterious ects on economy nation.State and federal leaders need tools that provide insight into which combination will greatest impact slowing disease at what point time it is reasonably safe start li ing restrictions everyday life.In present work, we outline modeling process...

Results All were associated scores lymphocytic inflammation ( P < 0.0001). Three that related the per unit...
Abstract We apply exploratory data analysis to some of the basic models neoclassical computational finance. These include portfolio selection algorithm Markowitz, capital market line Sharpe, and option pricing model Black-Scholes-Merton. demonstrate that Markowitzian assumption positive correlation expected return volatility is not supported by data.
