Comparing simple and multiple regression in R For simple regression, we will focus on how well weight predicts size. plot (mouse.data$weight, mouse,data$size),we specified mouse weight for the x-axis. Use the lm()(linear model)function to fit a line to the data. simple.regression<-lm(...

Multiple regression (an extension of simple linear regression) is used to predict the value of a dependent variable (also known as an outcome variable) based on the value of two or more independent variables (also known as predictor variables). For example, you could use multiple regression to...
• Consider non-linear regression (see options under trend-line) • Transform the response variable, instead of Y use one of the following that best corrects the problem: • Log of y • y to power of a constant, e.g. • Reciprocal of y or 1/y y 2 o r y 0 ...

all of which had sample sizes larger than 100. Based on these large sample sizes, we assumed that it would be reasonable to view the reported responses rates as a continuously valued outcome variable and use linear regression for analysis. An examination of a scatter plot of residuals against ...
(1,802 self-report CM cases and 7,208 controls) and on the X-axis we plot the log(OR) and standard error from a fixed-effects inverse-variance weighted meta-analysis of log(OR) effect-sizes derived from the logistic regression GWAS for confirmed melanoma cases listed in Supplementary Table...
