Missing data arise in many situations and pose more than a technical problem to the analyst. Software applications often require complete datasets, but more importantly, incomplete or missing observations may impact on the validity of the statistical analysis. Ad-hoc solutions, such as case or listwise deletion, mean imputation, and simple regression methods can lead to severe bias if the popul...

Refractive index control of benzocyclobutene (BCB 4024-40) is achieved by facilitating different conditions during the thermal curing of BCB film. Refractive index (RI) change of 1.49% is obtained with curing of BCB film using an oven, while the RI change is 0.1% when the BCB is cured using a hotplate. The two different curing methods exhibit a temperature dependent refractive index change of t...

Fully nonparametric methods for regression from functional data have poor accuracy from a statistical viewpoint, reflecting the fact that their convergence rates are slower than nonparametric rates for the estimation of high-dimensional functions. This difficulty has led to an emphasis on the so-called functional linear model, which is much more flexible than common linear models in finite dime...

conclusions our study suggests that the personality traits of patients with ms and healthy individuals are not significantly different. patients with ms are likely to use the same coping strategies as healthy individuals, except in the subscale of distancing. results no significant differences in personality characteristics were observed between patients and healthy controls (all p > 0.05). onl...

Several studies have reported a positive relation of baseline body mass index (BMI) with multiple myeloma, but data on other correlates of energy balance are limited. We undertook the present analyses to further examine the role of energy balance in multiple myeloma etiology in two large prospective cohorts with biennially updated exposure data. We followed members of the Nurses' Health Study a...

Conventional multiple description coding (MDC) is a source coding technique which provides resilience against packet loss. On the other hand, the correlation introduced between descriptions can be used to combat bit errors as well. While the latter feature of MDC has been attested and exploited in prior work, only few attempts have been made to design MDC with higher bit error resilience abilit...

The optimization criterion and a practically feasible new algorithm is stated for the optimization of the index assignments of a multiple description unconstrained vector quantizer with an arbitrary number of descriptions. In the simulations, the index-optimized multiple description vector quantizer achieves significant gains in source SNR over scalar multiple description schemes.
