  1. 1 de may. de 2020 · 93. 3.7K views 3 years ago. Tres partículas cargadas se encuentran en una línea recta y separadas por una distancia d, como se ve en la figura. Se mantienen fijas las cargas 𝑞1 y 𝑞2 y son de...

  2. The OPLS class is intended for exploratory modeling, that is not for the creation of predictors. Therefore there is a built-in k-fold cross-validation loop and Q2y is an average over the folds. console.log(model.model[0].Q2y); should give 0.9209227614652857.

  4. 9 de ago. de 2018 · Ejercicios Resueltos de la Ley de Coulomb. Veamos ahora una serie de ejercicios para entender mucho mejor el tema. Nota: - Si las cargas son de signo opuesto (+ y –), la fuerza "F" será negativa, lo que indica una fuerza de atracción.

  5. 8 de nov. de 2020 · We have $Q2Y \in [0,1]$, and the higher the Q2Y, the better the performance. Models trained on datasets with a larger number of features compared with the number of samples can be prone to overfitting : in that case, high Q2Y values are obtained by chance only.

  6. 8 de nov. de 2020 · Character vector: the following plots are available: 'correlation': Variable correlations with the components, 'outlier': Observation diagnostics (score and orthogonal distances), 'overview': Model overview showing R2Ycum and Q2cum (or 'Variance explained' for PCA), 'permutation': Scatterplot of R2Y and Q2Y actual and simulated models after random permutation of response values; 'predict-train ...
