Hi Angela, I believe you should introduce only df as parameters; t distribution as by default mean=0; see this example.
> x<-rt(100,10) > ks.test(x, "pt",10) One-sample Kolmogorov-Smirnov test data: x D = 0.1414, p-value = 0.03671 alternative hypothesis: two.sided Ciao Vito you wrote: Good morning, I have to apply the Ks test with the the t distribution. I know I have to write ks.test(data_name,"distribution_name", parameters..) but I don't know what is the name fot t distribution and which parameters to introduce? may be mean=0 and freedom degrees in my case? Thank you for helping me. Angela Re ===== Diventare costruttori di soluzioni Became solutions' constructors "The business of the statistician is to catalyze the scientific learning process."
