1 误差平方和(SSE The sum of squares due to error):¶ 举例:(下图中数据-0.2, 0.4, -0.8, 1.3, -0.7, 均为真实值和预测值的差) 在k-means中的应用: 公式各部分内容: 上图中: k=2 SSE图最终的结果,对图松散度的衡量.(eg:SSE(左图)<SSE(右图)) SSE随着聚类迭代,其值会越来越小,直到最后趋...
least squares (redirected fromSum of squared error) Thesaurus Medical Acronyms least squares pl.n.Statistics A method of determining the curve that best describes the relationship between expected and observed sets of data by minimizing the sums of the squares of deviation between observed and expecte...
Focus first on the sum-of-squares (SS) column with no repeated measures: The first row shows the interaction of rows and columns. It quantifies how much variation is due to the fact that the differences between rows are not the same for all columns. Equivalently, it quantifies how much...
Tlie inteival in (b) is wider because of a laiger ciitical value due to a lower significance level. Since 0.50 lies inside the 95% confidence interval forp, we caimot reject the null hypothesis at a 5% significance level. The size is given by Pr(0 — 0.5| .02), where the ...
asuch as the linear function, the two-factor interaction(2FI) function, and the second-order polynomial function, adequately fits the data, as the largestportion of the error sum of squares is not due to lack of fit, the p-value should be large (.0.05). 例如线性函数,二因素互作用(2FI...

This study also concludes that the GPR and LSSVM models overfit because of moderate to problematic multicollinearity in assessing ground vibration during blasting.Similar content being viewed by others Prediction of ground vibration due to mine blasting in a surface lead–zinc mine using machine ...
performed by assessment of statistical parameters such as model F-value, lack of fit F-value, coefficient of determination (R2), adjusted R-squared (R2Adj), predicted R-squared (R2Pred), predicted residual error sum of squares (PRESS) and adequate precision (AP). Analysis of variance (ANOVA...
Minimizing mortality losses due to multiple stress and obtaining maximum performance are the production goals for newly received cattle. In recent years, vaccination and metaphylaxis treatment significantly decreased the mortality rate of newly received cattle, while the growth block induced by treatment ...
The analysis separates the sum of squares into two parts viz, a part due to regression and a part due to error. Unfortunately, it is not practicable to present the complete computer output here. The non-orthogonal structure of the data strictly requires a different standard error for each ...
