某工程师想要评估三种不同金属的烧结时间与抗压强度之间的关系。该工程师分别度量了每种烧结时间下(100 分钟、150 分钟 和 200 分钟),每种金属类型的五个样品的抗压强度。 该工程师执行了一般线性模型 (GLM) 方差分析,并在输出中包含了主效应图。打开样本数据烧结时间.MTW.选择统计 ...
I have a question about the output of my glm model WITHOUT an intercept. I am comparing the number of infected leaves on plants in different months. In the case of a model WITH an intercept (using the default log link of the Poisson model), the (Intercept) should represent the log of ...
How to plot Kolmogorov Smirnov Chart in R? How to Interpret ROC Curve? Concordance and Discordance What is Somers-D Statistic? What is Gini Coefficient? Conclusion 1. Introduction: Building The Logistic Model To show the use of evaluation metrics, I need a classification model. So, let’s bu...
method: smoothing method to be used. Possible values are lm, glm, gam, loess, rlm. method = “loess”: This is the default value for small number of observations. It computes a smooth local regression. You can read more aboutloessusing the R code?loess. ...

In case you want to learn more abouttypical R programming error messagesand the handling of these errors, you may also have a look at the following YouTube video. In the video, the speaker Andres Karjus explains some common error messages that beginners often get and how to quickly figure ...
As a last step, we are going to plot theROC curveand calculate theAUC(area under the curve) which are typical performance measurements for a binary classifier. The ROC is a curve generated by plotting the true positive rate (TPR) against the false positive rate (FPR) at various threshold ...

We recorded all vascular plants for each plot with uniform size (20脳20m). Redundancy analysis (RDA) with forward selection procedure was used to test the species composition-environmental relationship. Generalized linear model (GLM) assessed the importance of environmental variables as predictors of ...
