Lineare Regression Zusammenfassung Die Korrelation zweier quantitativer Variablen ist ein Maß ihres linearen Zusammenhangs. Auch die lineare Regression analysiert den linearen Zusammenhang von Variablen, um die Werte einer Zielvariable (Kriterium) durch die Werte anderer Variablen (Prädiktoren...
Das „Was-man-wissen-sollte-Kapitel“ wird mit der bivariaten linearen Regression fortgesetzt. Auch diese gehört typischerweise zur Grundausbildung in Statistik. Da diese Methode aber im Kap. 3 direkt zur multiplen Regression erweitert wird, wird die bivariate lineare Regression ausführlicher ...
Come osservato in precedenza, la metrica di R al quadrato è una misura di quanto bene i punti di dati effettivi bene la retta di regressione calcolata. In termini matematici, R al quadrato è definito come R2 = 1 - (SSres / SStot). Il termine SSres viene solitamente chi...

The survival data of the prognostic factors were evaluated by univariate and multivariate Cox regression models. The P-values of p0.05 in all cases were considered to indicate a statistically significant result. RESULTS Expression of Pyk2, Pyk2[pY402] and Pyk2[pY881] was upregulated in NSCLC ...
By using multiple frequency excitation, sensors can be used to measure multiple quantities in one process, if different effects can be separated due to their different spectral behavior. A common evaluation method is the model-based approach together with complex nonlinear least-square regression of ...
Material and methods: We identified 14,597 non-small-cell lung cancer (NSCLC) patients with performance status <3 during 2013-2018 in the Danish Lung Cancer Registry. Multivariate logistic regression models were used to estimate Odds Ratios (ORs) and 95% confidenc...
In this study, we used data on raptors electrocuted on poles to develop a predictive model of raptor electrocution risk throughout an extensive geographical area in north‐western Spain, using boosted regression trees. With the best‐fitting model, we predicted the hazard of a set of 188,741 ...
