Hej, tack för blogg som hjälper många med sina statistiska ”problem” jag håller på med min B- uppsats och har använt mig av en logistisk regression, har använt 4 oberoende variabler och 2 beroende och resultatet blev att effekterna inte är statistiskt signifikanta, nu har jag fastnat i resultatet där jag måste beskriva vad de siffrorna jag har fått fram betyder och varför jag The Logistic Regression is a regression model in which the response variable (dependent variable) has categorical values such as True/False or 0/1. It actually measures the probability of a binary response as the value of response variable based on the mathematical equation relating it with the predictor variables. Se hela listan på stats.idre.ucla.edu Logistic regression is a method for fitting a regression curve, y = f (x), when y is a categorical variable. The typical use of this model is predicting y given a set of predictors x. The predictors can be continuous, categorical or a mix of both.
