Variance stabilization and normalization for one-color microarray data using a data-driven multiscale approach

Variance stabilization and normalization for one-color microarray data using a data-driven multiscale approach

MOTIVATION Many standard statistical techniques are effective on data that are normally distributed with constant variance. Microarray data typically violate these assumptions since they come from non-Gaussian distributions with a non-trivial mean-variance relationship. Several methods have been proposed that transform microarray data to stabilize variance and draw its distribution towards the ...

cDNA Microarray Data Normalization

a new approach to credibility premium for zero-inflated poisson models for panel data

هدف اصلی از این تحقیق به دست آوردن و مقایسه حق بیمه باورمندی در مدل های شمارشی گزارش نشده برای داده های طولی می باشد. در این تحقیق حق بیمه های پبش گویی بر اساس توابع ضرر مربع خطا و نمایی محاسبه شده و با هم مقایسه می شود. تمایل به گرفتن پاداش و جایزه یکی از دلایل مهم برای گزارش ندادن تصادفات می باشد و افراد برای استفاده از تخفیف اغلب از گزارش تصادفات با هزینه پائین خودداری می کنند، در این تحقیق ...

A new approach for normalization of DNA-microarray data

Signal data from DNA-microarray “chip” technology contains various artifacts from the fabrication process and it is inherently noisy. In order to detect the systematic errors and to reduce the noise contained in the experimental data, replications of the experiments are made. Therefore the crucial point in obtaining biological information out of the experimental data is the use of advanced norm...

A Data-Driven Approach for Mapping Multivariate Data to Color

A wide variety of color schemes have been devised for mapping scalar data to color. Some use the data value to index a color scale. Others assign colors to different, usually blended disjoint materials, to handle areas where materials overlap. A number of methods can map low-dimensional data to color, however, these methods do not scale to higher dimensional data. Likewise, schemes that take a ...
