Association Between a Continuous Response and a Continuous Predictor
Description
These functions take a data frame with two numeric continuous columns "x" (predictor) and "y" (response), fit a univariate model, and return the R-squared of the observations versus the model predictions:
-
f_r2_pearson()
: Pearson's R-squared. -
f_r2_spearman()
: Spearman's R-squared. -
f_r2_glm_gaussian()
: Pearson's R-squared of a GLM model fitted withstats::glm()
, with formulay ~ s(x)
and familystats::gaussian(link = "identity")
. -
f_r2_glm_gaussian_poly2()
: Pearson's R-squared of a GLM model fitted withstats::glm()
, with formulay ~ stats::poly(x, degree = 2, raw = TRUE)
and familystats::gaussian(link = "identity")
. -
f_r2_gam_gaussian()
: Pearson's R-squared of a GAM model fitted withmgcv::gam()
, with formulay ~ s(x)
and familystats::gaussian(link = "identity")
. -
f_r2_rpart()
: Pearson's R-squared of a Recursive Partition Tree fitted withrpart::rpart()
with formulay ~ x
. -
f_r2_rf()
: Pearson's R-squared of a 100 trees Random Forest model fitted withranger::ranger()
and formulay ~ x
.
