Nettet10. feb. 2024 · There is nothing in maximum likelihood that helps us estimate how well we predict. Actually, it is possible to increase the likelihood beyond any bound, without increasing predictive accuracy at all. To illustrate the last point about increasing likelihood without increasing predictive quality, let me give an example. Nettet24. nov. 2024 · Accuracy can be defined as the percentage of correct predictions made by our classification model. The formula is: Accuracy = Number of Correct predictions/number of rows in data. Which can also be written as: Accuracy = (TP+TN)/number of rows in data. So, for our example: Accuracy = 7+480/500 = 487/500 = 0.974. redness on chest and faceNettet12. feb. 2024 · I am implementing logistic regression in Python and am at the point where I am writing code for maximum likelihood estimation for a parameter vector according to … redness on feet and ankles
