I did a linear correlation of data using glm.fit and stored the output in the object "f": f <- glm.fit(x, y, w) I am intereseted in estimating the quality of the correlation. I am used to do it using pearson correlation coefficient "r" or "r^2". Can I extract this coefficient from the output of glm.fit? Is there another number in the output of glm.fit that represents the quality of the correlation?
Here is a printout of the object f: $coefficients [1] 95772.92 $residuals [1] -5146.208 -17221.948 -12743.726 -14536.236 -36311.931 -33651.931 [7] -75054.063 -73207.873 -136695.506 -142442.126 -268970.512 -260546.762 [13] -281117.024 -247116.524 9115.715 64791.715 $fitted.values [1] 74702.88 74702.88 149405.76 149405.76 299769.24 299769.24 [7] 598580.75 598580.75 1197161.51 1197161.51 2394323.01 2394323.01 [13] 4788646.02 4788646.02 57463752.29 57463752.29 $effects -81641362.05 -17217.24 -12734.32 -14526.83 -36293.05 -33633.05 -75016.37 -73170.18 -136620.11 -142366.73 -268819.73 -260395.98 <NA> -280815.45 -246814.95 12734.59 68410.59 $R [,1] [1,] -852.4472 $rank [1] 1 $qr $qr [,1] [1,] -8.524472e+02 [2,] 9.150126e-04 [3,] 1.830025e-03 [4,] 1.830025e-03 [5,] 3.671781e-03 [6,] 3.671781e-03 [7,] 7.331832e-03 [8,] 7.331832e-03 [9,] 1.466366e-02 [10,] 1.466366e-02 [11,] 2.932733e-02 [12,] 2.932733e-02 [13,] 5.865466e-02 [14,] 5.865466e-02 [15,] 7.038559e-01 [16,] 7.038559e-01 $rank [1] 1 $qraux [1] 1.000915 $pivot [1] 1 $tol [1] 1e-11 attr(,"class") [1] "qr" $family Family: gaussian Link function: identity $linear.predictors [1] 74702.88 74702.88 149405.76 149405.76 299769.24 299769.24 [7] 598580.75 598580.75 1197161.51 1197161.51 2394323.01 2394323.01 [13] 4788646.02 4788646.02 57463752.29 57463752.29 $deviance [1] 337719889404 $aic [1] 429.7723 $null.deviance [1] 5.570009e+15 $iter [1] 2 $weights [1] 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 $prior.weights [1] 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 $df.residual [1] 15 $df.null [1] 15 $y [1] 69556.67 57480.93 136662.03 134869.52 263457.31 266117.31 [7] 523526.69 525372.88 1060466.00 1054719.38 2125352.50 2133776.25 [13] 4507529.00 4541529.50 57472868.00 57528544.00 $converged [1] TRUE $boundary [1] FALSE > coefficients(f1) [1] 95772.92 -- View this message in context: http://r.789695.n4.nabble.com/glm-fit-and-pearson-s-correlation-coefficient-tp4369811p4369811.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
