Statistical Treatment of Clinical Investigations in Pediatric Cardiology
Children, 2021 This paper describes various statistical methods used by the author during multiple studies conducted by the author. Initially, the data were scrutinized to ensure normal distribution, and expressed as mean ± standard deviation (SD) or standard error of ...

Normality for Non-normal Distributions
Journal of Science and Mathematics Letters, 2020 It has been usually assumed that a sample data is normally distributed when the sample size is at least 30. This is the general rule in using central limit theorem based on the sample size being greater or equal to 30. Many literary works also assumed normality when sample size is at least 30. This study aims to determine the least required sample size

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

A Note on the Normal Distribution
The Annals of Mathematical Statistics, 1956 Let \(x_1, x_2,\ldots, x_n\) be independent and identically distributed with density \(f(x)\) and put \[ \bar x = \frac 1n \sum_{j=1}^n x_j,\quad \delta_k^2=\frac 1{2n-k} \sum_{j=1}^{n-k}(x_{j+1}-x_j)^2. \] Using results of \textit{E. Lukacs} [ Ann. Math. Stat. 13, 91--93 (1942; Zbl 0060.28509)] and \textit{J. F. Daly} [Ann. Math. Stat.

Central Nervous System Tumors Among Infants in Canada: A Report From CYP‐C
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) tumors in infants are rare, pose unique clinical challenges, and lack large‐scale evidence‐based data to guide management. This study seeks to describe CNS tumors in Canadian infants and to compare their outcomes with those of older children.

On the Regression Model for Generalized Normal Distributions
Entropy, 2021 The traditional linear regression model that assumes normal residuals is applied extensively in engineering and science. However, the normality assumption of the model residuals is often ineffective.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.
