The coefficient of determination is used in regression models to measure how much of the variance of one variable is explained by the variance of the other variable. A regression analysis helps you find the equation for the line of best fit, and you can use it to predict the value of one...
Pearson correlation coefficientregressionWe propose two simple regression models of Pearson correlation coefficient of two normal responses or binary responses to assess the effect of covariates of interest. Likelihood-based inference is established to estimate the regression coefficients, upon which bootstrap...
