In this work we investigate the hardness of a computational problem introduced in the recent work of Baumslag et al. [BFNSS11]. In particular, we study the Bn-LHN problem, which is a generalized version of the learning with errors (LWE) problem, instantiated with a particular family of non-abelian groups (free Burnside groups of exponent 3). In our main result, we demonstrate a random self-redu...

We consider random-design nonparametric regression model in which errors depend on predictors as well as on unobservable latent variables. Predictors and latent variables may be shortor long-range dependent. In this setup asymptotic distributions of the Nadaraya-Watson estimate of regression function are studied under various conditions. We prove that their form depends on three factors: amount...

In this work we investigate the hardness of a computational problem introduced in the recent work of Baumslag et al. in [3, 4]. In particular, we study the Bn-LHN problem, which is a generalized version of the learning with errors (LWE) problem, instantiated with a particular family of non-abelian groups (free Burnside groups of exponent 3).

OBJECTIVE This study examined the impact of pharmacists' perceptions of errors in dispensing, errors in communication, delays in prescription processing, efficiency and physical mobility in the pharmacy by practice setting and sociotechnical factors (i.e. pharmacy design, drive through pick-up window services and automated dispensing systems). SETTING Community pharmacy practice in the USA. ...

Spline smoothing provides a powerful tool for estimating nonparametric functions. Most of the past work is based on the assumption that the random errors are independent. Observations are often correlated in applications; e.g., time series data, spatial data and clustered data. It is well known that correlation greatly a ects the selection of smoothing parameters, which are critical to the perf...

A betweenness axiom states that if A and B are equally good then a mixture of A and B is equally good as well. This note demonstrates that the violations of the betweenness axiom documented in several experimental studies can be alternatively attributed to the effect of random errors.

goal: this study aims at analyzing and categorizing different grammatical errors including morpho-syntactic and syntactic errors in written narratives of mentally retarded students in tehran. the frequencies of errors are compared among students in different grades. method: descriptive-analytic method has been used. a test consisted of four picture stories have been administered to 125 students...

This paper compares the oral reading errors between the contextual sentences and random words among schoolchildren. Two sets of reading materials were developed to test the oral reading errors in 30 schoolchildren (10.00±1.44 years). Set A was comprised contextual sentences while Set B encompassed random words. The schoolchildren were asked to read both contextual sentences and random words rea...
