关于两组相关性的问题的讨论
|
|
各位大神们好，这里有两组数据，每一组有203个元素。这两组数据是非线性相关的，相关系数为-0.79！我这里想把它们通过某种变换或者映射（非线性变换或者非线性映射）从而使其变为线性相关（或者在高位空间里具有线性关系），不知有哪位大神做过这种研究，指导指导我！ 以下是我的数据及图片： x y -0.5536 0.7199 -5.2546 0.8618 -1.5117 0.8331 -1.5444 0.8452 -0.4414 0.8421 -0.5339 0.7830 -0.6138 0.8873 -0.6405 0.8844 -0.6979 0.7591 -0.7327 0.7865 -0.8112 0.6353 -0.7398 0.6515 -0.9072 0.7198 -1.0827 0.7750 -0.9182 0.7653 -0.9371 0.7695 -1.0705 0.7964 -1.1125 0.9016 -0.9844 0.7922 -0.9611 0.8654 -0.9753 2.4180 -0.9732 2.0243 -0.8829 1.7320 -1.0309 1.3685 -0.9628 1.2356 -0.8256 8.7787 -0.6666 5.7160 -0.6335 3.5184 -0.7000 2.1950 -0.6881 1.5542 -0.8761 1.5420 -0.9036 1.8980 -0.9606 2.4235 -1.2904 2.7662 -1.7987 3.1789 -2.5900 3.1690 -3.2058 3.8908 -4.0768 4.2503 -4.6836 4.8932 -5.9236 5.5886 -8.0228 6.0673 -9.2038 6.9691 -12.8271 6.5501 -15.1591 12.7484 -15.9533 10.1538 -16.1671 10.6984 -19.0237 15.0283 -21.5713 18.6697 -22.8884 19.4809 -24.9401 19.4284 -25.2505 20.4088 -24.7604 21.7619 -25.3835 19.8470 -26.4447 23.2087 -24.7506 21.8005 -24.3948 22.6811 -22.5925 23.8353 -21.9489 24.9393 -22.8061 23.7268 -23.4478 26.4030 -23.3974 27.0340 -24.1355 26.9872 -24.8314 29.8053 -25.1862 38.1054 -25.3765 38.4528 -24.8294 42.0495 -24.4944 48.3982 -23.3448 54.0413 -23.4569 57.3519 -23.4766 61.5333 -24.6802 65.1147 -25.3585 64.2174 -26.1443 64.3091 -26.2711 61.5023 -26.8793 65.7972 -27.0618 67.7747 -27.1012 69.2909 -26.9145 67.7819 -27.5984 66.6373 -28.2706 63.4622 -29.7863 59.2800 -38.3548 55.5799 -35.5020 53.5482 -33.5247 53.3568 -32.4846 51.6044 -32.0422 50.9948 -31.9955 48.6813 -32.6080 47.4047 -32.1607 48.5805 -32.1328 43.8261 -32.7745 42.5534 -32.7297 43.5628 -32.9302 44.3431 -32.2738 46.5188 -32.0929 47.9199 -31.2253 49.4136 -31.1027 49.4494 -30.8878 49.2809 -30.1562 49.2318 -29.4241 47.7263 -29.8331 43.3821 -33.9951 40.7655 -32.1484 38.7439 -31.2201 35.2221 -30.7243 32.5501 -30.3972 33.7487 -31.0571 36.3333 -32.3824 35.7169 -34.0880 30.6410 -34.1848 29.3508 -33.7396 30.0124 -32.7552 31.5310 -32.7480 33.7693 -34.1436 35.7057 -33.3877 37.6583 -33.4834 39.6504 -34.3572 41.7516 -35.3265 45.6205 -33.5669 49.0954 -33.3496 51.6580 -32.4224 52.4022 -34.9690 54.6455 -34.9217 54.4960 -35.8462 52.4176 -40.0468 47.6523 -41.0440 47.3380 -43.5867 44.5674 -46.9101 38.8434 -50.7294 35.4712 -48.1282 33.0485 -50.0920 31.7089 -50.9602 31.1300 -43.8894 30.9834 -45.3814 30.5182 -41.7525 28.7579 -43.3972 28.0316 -38.1027 27.3814 -34.6450 26.6044 -34.6210 26.0143 -33.1391 25.4117 -32.7942 24.5718 -32.7460 24.0039 -32.5457 18.1326 -32.6102 25.3670 -32.3011 25.0442 -31.8181 24.4145 -31.3017 24.6921 -30.6844 25.0839 -30.0108 25.5799 -29.4273 25.0093 -28.4910 23.6927 -27.2749 24.1029 -26.1116 24.3163 -24.7119 24.7590 -23.9302 24.5573 -22.6550 23.8576 -20.7964 23.2004 -19.7420 22.5244 -18.3914 22.3202 -16.8216 20.2179 -16.4347 20.2440 -16.0156 19.1300 -14.4494 18.1995 -13.7167 17.7119 -13.1110 16.3263 -12.7657 15.8665 -12.5822 15.2306 -12.0432 14.1616 -11.1641 12.7763 -10.4359 11.8776 -10.4037 10.5114 -10.2846 9.4361 -10.1860 8.6959 -10.0696 8.4355 -10.0884 8.2469 -10.0847 8.5976 -9.8367 8.9477 -9.2655 8.9057 -8.8133 8.8371 -8.2835 8.6544 -7.8595 8.3345 -7.5696 7.7414 -7.1498 6.8944 -6.7204 6.4640 -6.2409 7.0701 -5.7537 7.1105 -5.1959 7.3993 -4.5220 7.3576 -3.9347 7.0260 -3.3550 7.1198 -2.9929 7.2822 -2.7826 7.5135 -3.0122 7.6875 -2.9036 7.9254 -2.6690 8.1188 -2.9341 7.8058 -2.1476 7.1308 -1.1797 6.6019 -0.5211 6.1383 -0.2349 5.8223 -0.3578 5.7678 0.0064 5.4744 -0.2745 5.1429  12K]H`@P{UBW7Q9WGFMW)EA.png |
