Sensitivity analysis in linear regression
Web1. it's basically a partial derivative with respect to a parameter or input in a very broad sense. for instance, it could measure the impact of the coefficient change 10% up or down. it's a way to measure the model risk. if your forecast or output is very sensitive to a coefficient it tells you that there's a high model risk. – Aksakal. WebThus, the appropriate link is the log odds transformation (the logit). Then if there are n binomial observations of the form for , where the expected value of the random variable associated with th observation, , is .The logistic regression model for association of on the values of k risk factors is such that [] and the equation of success probability is The linear …
