Calculo de distância euclidiana<br>
<br>
Bom dia. Tenho um arquivo que ajusto um modelo de regressão gerando
três betas para cada árvore.<br>
<br>
Tenho casos de ter a medição de mil árvores. Após fazer os ajustes
passo a ter beta 0, beta 1 e beta 2 para cada árvore.<br>
<br>
Gostaria de calcular a distância euclidiana do beta 0 com o beta 0,
beta 1 com o beta 1 e beta 2 com o beta 2, entre todas as árvores.<br>
<br>
O meu objetivo é ter uma matriz de distância euclidiana entre todos
os betas de todas as árvores para saber por exemplo qual árvore é
mais próxima da árvore de número 21.<br>
<br>
Abaixo um pedaço do arquivo.<br>
<br>
Obrigado pela ajuda.<br>
