WitrynaMethods: A total of 535 bladder cancer patients and 649 health controls were recruited for our study. MDM2 SNP309 T>G polymorphism was genotyped by polymerase chain reaction-ligase detection reaction method. Logistic regression was used to analyze the relationship between the genotype and susceptibility of bladder cancer.

WitrynaIn a glm where you have to estimate both a mean and dispersion parameter, you should see the t -distribution used. For a standard linear regression, you assume the error term is normally distributed. Here, the variance parameter has to be estimated - hence the use of the t -distribution for the test statistic. WitrynaIf the dependent variable is categorical, a logistic regression is used. You can easily perform a regression analysis in the linear regression calculator here on DATAtab.
