Data collected from complex sample surveys are frequently used in secondary data analysis. The analysis of such data using standard statistical software yields biased point estimates of parameters and incorrect standard errors as a result of unequal probabilities of selection of observations, stratification and clustering, and unit nonresponse. The appropriate analysis of data from complex samp...

The exact likelihood function of a Gaussian vector autoregressive-moving average (VARMA) model is evaluated in two non standard cases: (a) a parsimonious structured form, such as obtained in the echelon form structure or the scalar component model (SCM) structure; (b) a partially non stationary (unit root) model in error-correction form. The starting point is Shea’s algorithm (1987, 1989) for s...

the significant consumption of gas in the world results in the emission of greenhouse gases into atmosphere. abadan refinery has always been the biggest and oldest oil refinery in the middle east and has a variety of refined products. after six months of collecting data about pollutant concentration emitted from a stack of old furnaces of units 75 and new unit 200, the emission factor of the po...

Sampling recommendations were developed for a potato bait sampling method used to estimate garden symphylan (Scutigerella immaculata Newport) densities in western Oregon. Sample size requirements were developed using Taylor's power law to describe the relationship between sample means and variances. Developed sampling recommendations performed well at sample sizes of 30 and greater, when valida...

This paper considers estimation and inference in panel vector autoregressions (PVARs) with fixed effects when the time dimension of the panel is finite, and the cross-sectional dimension is large. A Maximum Likelihood (ML) estimator based on a transformed likelihood function is proposed and shown to be consistent and asymptotically normally distributed irrespective of the unit root and cointegr...

Biobanks are key research infrastructures aimed at the collection, storage, processing, and sharing of high-quality human biological samples associated data for research, diagnosis, personalized medicine. The Biobank Translational Digital Medicine Unit European Institute Oncology (IEO) is a landmark in this field. collaborate with clinical divisions, internal external groups, industry, supporti...
