Logistic Regression and Linear Discriminant Analyses in Evaluating Factors Associated with Asthma Prevalence among 10- to 12-Years-Old Children: Divergence and Similarity of the Two Statistical Methods

Abstract: Logistic regression and discriminant analyses are both applied in order to predict the probability of a specific categorical outcome based upon several explanatory variables (predictors). The aim of this work is to evaluate the convergence of these two methods when they are applied in data from the health sciences. For this purpose, we modeled the association of several factors with the prevalence of asthma symptoms with both the two methods and compared the result. In conclusion, logistic and discriminant ana… Show more

“…The first step in data analysis calculated two classification models per age group to predict U20 player status (professional or non-professional): one for GMP (40m sprint, agility, counter movement jump, Yo-Yo intermittent recovery test) and one for SMP (dribbling, passing, juggling, shooting). To calculate the likelihood of each individual being categorized as a professional or non-professional player, each of the models used robust classification from binary logistic regression (BLR) in R (Antonogeorgos, Panagiotakos, Priftis, & Tzonou, 2009; R Core Team, 2017). The subsequent receiver operating characteristic (ROC) from the R package pROC determined the 14.0 ± 7.1* 9.0 ± 6.2 10.4 ± 6.8 16.6 ± 6.6* 11.5 ± 7.3 12.9 ± 7.5 Shooting (points) 6.9 ± 3.4 6.9 ± 2.8 6.9 ± 2.9 8.3 ± 3.3 7.7 ± 3.2 7.9 ± 3.…”

“…Hill and Lewicki (2006) claimed that a single outlier is capable of considerably changing the slope of the regression line and, consequently, affects the value of the correlation coefficient. Antonogeorgos et al (2009) suggested that outliers should be detected and removed by analyzing standardized residuals because outliers can distort the valid estimation of the logistic coefficients. We examined the standardized residuals to remove outliers.…”

“…Linear DFA with a binary (categorical) dependent variable represents the simplest form of DFA in which a single discriminant function is derived. In terms of classification accuracy and predictor extraction, it is similar with binary logistic regression, particularly in sufficiently large populations (ie, >50) . In lieu of its capability to produce a predictive linear function that can categorize sizeable populations with considerable accuracy compared with other methods, linear DFA represents a viable approach to our study's aims.…”
