Selecting risk factors: A comparison of discriminant analysis, logistic regression and cox's regression model using data from the tromsø heart study
Abstract For comparative evaluation, discriminant analysis, logistic regression and Cox's model were used to select risk factors for total and coronary deaths among 6595 men aged 20–49 followed for 9 years. Groups with mortality between 5 and 93 per 1000 were considered. Discriminant analysis s...
