The discussion on the use and misuse of p-values in 2016 by the American Statistician Association was a timely assertion that statistical concept should be properly used in science. Some researchers, especially the economists, who adopt significance testing and p-values to report their results, ...
Example 2 – Interpreting Regression Results of ANOVA Table in Excel In the middle of the output, you’ll see the ANOVA (Analysis of Variance) Table. The terms used in the table are as follows. df (degrees of freedom): df refers to degrees of freedom. It can be calculated using the ...
values of the independent variable. Excel, the popular spreadsheet program by Microsoft, provides a simple yet powerful set of tools to perform linear regression analysis. In this article, we will explore how you can do linear regression in Excel, step by step, and make sense of the results....

These regression models involve the use of an optimization algorithm to find a set of coefficients for each input to the model that minimizes the prediction error. Because the models are linear and well understood, efficient optimization algorithms can be used. In the case of linear regression, ...
This "quick start" guide shows you how to carry out multiple regression using Stata, as well as how to interpret and report the results from this test. However, before we introduce you to this procedure, you need to understand the different assumptions that your data must meet in order for...
s decision to report a certain performance or risk metric in its factsheets. However, performance measures may be disclosed via multiple channels before factsheets’ release on Morningstar. Hence, I use “dissemination” when I discuss the empirical results on the repeated disclosure of measures ...
Research articles based on the Surveillance, Epidemiology, and End Results (SEER) (not SEER-Medicare) that had been published in journals from 1998 to 2022 searched by PubMed. The joinpoint analysis program chose the most suitable loglinear regression model to detect calendar years (known as “...
results suggest that online convenience samples may display more positive dispositions towards COVID-19 prevention behaviours being studied than would samples drawn using more representative means. Adjusting results for demographic covariates frequently increased rather than decreased bias, suggesting that ...
Using one of the several formulas, the end result will be a numerical output between -1 and +1. Let’s say you are interested in the relationship between two variables, Variable A and Variable B. Results close to +1 indicate a positive correlation, meaning as Variable A increases, ...
