Training models on the original train dataset caused models to overfit the majority class. Thus, they had poor recall or sensitivity, precision and F1-score values which are crucial in detecting positive, false positives and false negative classes for T2DM. Also, time it took a model to train...
该研究是追溯性的,而不是设计性的实验,因此尽管可以推断出相关性,但不能因果关系。 数据集中的特征既是连续的又是分类的。 目标:探索性别,体重和年龄之间的相关性 第0部分:设置 library(ggplot2) library(dplyr) library(Rgraphviz) library(knitr) library(grid) library(gridExtra) load("brfss2013.RData") #...

This study demonstrates the potentiality of machine learning coupled with imbalanced data modeling approaches for predicting asthma from a large survey dataset. We conclude that the findings could guide early screening of at-risk asthma patients and designing appropriate interventi...
The dataset had variables that were grouped as, predisposing, reinforcing or enabling constructs of PRECEDE model. The analysis showed that race, body mass indexes, and high cholesterol, were strongly associated with having hypertension. For poor hypertension control only race, body mass index, high...
