Witryna1 sty 2012 · Like linear regression, estimates of the logistic regression are sensitive to the unusual observations: outliers, high leverage, and influential observations. Numerical examples and... WitrynaLogistic regression can be sensitive to outliers and noisy data, while decision trees can handle them better by splitting the data into smaller regions. Logistic regression tends to perform well when the number of features is small, while decision trees can handle a larger number of features. Both logistic regression and decision trees can ...
machine learning - How regularization helps to get rid of outliers ...
WitrynaThere are three ways we can find and evaluate outlier points: 1) Leverage points These are points with outlying predictor values (the X's). It doesn't have anything to do with what the response variable (Y) is; we just look at these points because they potentially have a significant impact on coefficient estimates and standard errors. What to do: Witryna14 kwi 2015 · Specifically, logistic regression is a classical model in statistics literature. (See, What does the name "Logistic Regression" mean? for the naming.) There are many important concept related to logistic loss, such as maximize log likelihood estimation, likelihood ratio tests, as well as assumptions on binomial.

How does outlier impact logistic regression? - Cross Validated
WitrynaI have multivariable logistic regression results: With outlier in model p-values are as follows (age:0.044, ethnicity:0.054, knowledge composite variable: 0.059. When I take out the outlier, values become (age:0.424, eth: 0.039, knowledge: 0.074) So by taking out the outlier, 2 variables become less significant while one becomes more significant. Witryna9 kwi 2024 · Logistic regression, as one of the special cases of generalized linear model, has important role in multi-disciplinary fields for its powerful interpretability. ... The latter is less sensitive to the outlier. Then Minkowski distances (A generalization of the Euclidean and the Manhattan metric) between the observations are computed to … Witryna1 sty 2011 · Afterwards, logistic regression analyses were conducted and model outliers were detected: cases with a Cook's distance value greater than 1 (7 in total) were eliminated (Cousineau & Chartier, 2010 ... terrick moussa
