Significance of slope of regression
WebAug 3, 2010 · In a simple linear regression, we might use their pulse rate as a predictor. We’d have the theoretical equation: ˆBP =β0 +β1P ulse B P ^ = β 0 + β 1 P u l s e. …then fit that to our sample data to get the estimated equation: ˆBP = b0 +b1P ulse B P ^ = b 0 + b 1 P u l s e. According to R, those coefficients are: WebNov 27, 2024 · And maybe an F-test of overall significance in regression analysis. For some reason, I'm not interested in finding confidence intervals for p and q. But p-values or t-statistics or whatever are of more interest for me to calculate. So that. Ho : p statistically insignificant H1 : p statistically significant. Same for q. And an F-test:

You are right, they are not the same. You can look at correlation as a standardized slope between the x and y, since correlation is covariance divided by the respective standard deviations: r x y = C o v ( x, y) σ x σ y. The constant b doesn't tell us anything directly about the correlation. You can have a small value of b, with y and x ...
