Witryna25 lip 2024 · Not only is Stata syntax consistent and simple to use to perform logistic regressions; Stata is methodologically are rigorous and is backed up by model validation and post-estimation tests. Current logistic regression results from Stata were reliable – accuracy of 78% and area under ROC of 81%. WitrynaA statistically significant coefficient or model fit doesn’t really tell you whether the model fits the data well either. Its like with linear regression, you could have something really nonlinear like y=x 3 and if you fit a linear function to the data, the coefficient/model will still be significant, but the fit is not good. Same applies to logistic.

WitrynaI trained a logistic regresion model using glm () model1 <- glm (formula= target ~ a + b, data=df, family=binomial) Now I'm trying to predict the output (for the example, the same data should suffice) predict (model1, newdata=df, type="response") This generates a vector of probability numbers. But I want to predict the actual class. Witryna26 lis 2024 · Hi I have a question about the sensitivity and specificity. Situation: I have a estimation result using multinomial logit model. I want to calculate the sensitivity and specificity. Question: Whether the following process is problematic or not. Get the predicted choice probabilities for each outcome. Find the maximum predicted … Witryna6 kwi 2024 · Sensitivity or recall is important when you are concerned with identifying positive outcomes and the cost of a false positive is low — meaning we are fine … pottruck health
