Question
Download Solution PDFजर x आणि y मधील सहसंबंध गुणांक 0.5 असेल आणि y चा x वरील प्रतिगमन गुणांक 0.5 असेल, तर x चा y वरील प्रतिगमन गुणांक किती असेल?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFx आणि y मधील सहसंबंध गुणांक (rxy) = 0.5
y चा x वरील प्रतिगमन गुणांक (byx) = 0.5
x चा y वरील प्रतिगमन गुणांक (bxy) = \({r^2 \over b_{yx}}\) = \({(0.5)^2 \over 0.5} = 0.5\)
x आणि y मधील सहसंबंध गुणांक (rxy) = \(\sqrt {{b_{xy}} × {b_{yx}}}\)
किंवा, rxy2 = bxy x byx
किंवा, bxy = \({r^2 \over b_{yx}}\)
म्हणून, x चा y वरील प्रतिगमन गुणांकाचा आवश्यक मूल्य 0.5 आहे
