Use graphs as an alternative to tables with many entries; do not duplicate data in graphs and tables.
We recognize that there are a number of schools of differing statistical philosophy, and we take these differences into account. Nevertheless, over the years, a number of specific items have been Volume , Number 1 raised repeatedly by statisticians when reviewing manuscripts.
The Editors have compiled a list of these and present them in the form of guidelines, with the intent of being helpful to authors, not prescriptive. The guidelines have been formulated as a checklist and appear twice yearly, in the January and July issues.
Thoracic Surgery. New York: Churchill Livingstone; Checklist Notation and terminology. Distinguish between a variable, an item that can take on different values for each subject or observation, such as temperature and blood pressure, and a parameter, a constant, such as the mean.
Distinguish between prevalence, a proportion of subjects or observations, and incidence or rate, a quantity expressed per unit of time. Increasingly, approximations to parameter estimation and measures of uncertainty are being supplemented by computer-intensive resampling bootstrap methods. Presentation of time-related events. In most circumstances, we recommend that the following information accompany presentations of time-related events: point estimates, preferably at the time of each event using a product limit method; asymmetric confidence limits at periodic intervals; and the number of patients at risk at periodic intervals.
Nonrandomized comparisons. Unlike experimental comparison studies that nearly always should be randomized, randomization in the clinical setting is often neither feasible nor ethical.
Increasingly, multivariable matching methods for adjusting for ascertainable selection bias are becoming prevalent, well understood, and accessible eg, use of propensity scores. Multiple group comparisons and repeated measurements. In comparing three or more groups, statistical methods appropriate for multiple group comparisons and contrasts should be employed.
If these groups have a natural ordinal relationship one with another, then methods that account for trend should be employed. When multiple measurements are obtained across time in the same patient or subject, methods of longitudinal data analyses a relatively new field of statistics that has supplanted traditional repeated measures methodology are recommended.
Multivariable analyses. The book makes use of study aids such as tables, charts, figures, and formulae to accompany the theory. It features several exercises at the end of each chapter, varying in difficulty levels.
This allows students to practise what they have learnt. This book also provides the solutions in detail and highlights each step for better understanding. The appendices are an additional help to students and stresses on significant points of Chi square, significant points of F, areas under Standard Normal Curve, and more.
Students will also learn the techniques of solving numerical problems. This book will also teach them how to collect and analyse data and arrive at conclusions from the material gathered.
The book has 53 figures, exercises, tables, and theoretical questions. The book also has unsolved and solved problems. Statistical Methods Volume 1 And 2 is well-organised and divided in 19 chapters for convenient study and reference.
