Given these two kinds of data set, and data set2 was obtained through the weighted Euclidean formula. Can we estimate the weight parameter for each variable in R based on the steepest descent method ? Thanks very much. data set 1: 9 164 78 0 0 32.8 0.148 45 4 134 72 0 0 23.8 0.277 60 5 166 72 19 175 25.8 0.587 51 1 79 60 42 48 43.5 0.678 23 3 78 50 32 88 31 0.248 26 7 147 76 0 0 39.4 0.257 43 1 71 62 0 0 21.8 0.416 26 4 146 85 27 100 28.9 0.189 27 2 91 62 0 0 27.3 0.525 22 12 92 62 7 258 27.6 0.926 44 9 119 80 35 0 29 0.263 29 1 119 88 41 170 45.3 0.507 26 6 87 80 0 0 23.2 0.084 32 9 164 84 21 0 30.8 0.831 32 ... ... data set 2: Pair No = 1 First Record = 153 Second Record = 362 Distance 0.195109293281901 Pair No = 2 First Record = 244 Second Record = 444 Distance 0.276686595232122 Pair No = 3 First Record = 102 Second Record = 349 Distance 0.117089030740308 Pair No = 4 First Record = 186 Second Record = 278 Distance 0.110082950942552 Pair No = 5 First Record = 85 Second Record = 362 Distance 0.163096250231904 Pair No = 6 First Record = 229 Second Record = 286 Distance 0.133259083865808 Pair No = 7 First Record = 157 Second Record = 372 Distance 0.0801890745331076 Pair No = 8 First Record = 400 Second Record = 440 Distance 0.180080273679888 Pair No = 9 First Record = 104 Second Record = 65 Distance 0.270852896379353 Pair No = 10 First Record = 339 Second Record = 504 Distance 0.0903208989422145 Pair No = 11 First Record = 243 Second Record = 472 Distance 0.15667825467493 Pair No = 12 First Record = 332 Second Record = 285 Distance 0.198595164521116 Pair No = 13 First Record = 235 Second Record = 254 Distance 0.274602506212988 Pair No = 14 First Record = 474 Second Record = 298 Distance 0.220495386986385 Pair No = 15 First Record = 192 Second Record = 186 Distance 0.128319782237726 Pair No = 16 First Record = 266 Second Record = 460 Distance 0.138253740286321 Pair No = 17 First Record = 357 Second Record = 211 Distance 0.112028810325944 Pair No = 18 First Record = 460 Second Record = 390 Distance 0.125758538023743 Pair No = 19 First Record = 332 Second Record = 31 Distance 0.197584497870041 Pair No = 20 First Record = 264 Second Record = 491 Distance 0.143571812789276 ... ...
