More details on parametric methods for survival analysis can be found in Hosmer and Lemeshow and Lee and Wang 13 We focus here on two nonparametric methods which make no assumptions about how the probability that a person develops the event changes over time Using nonparametric methods we estimate and plot the survival distribution or the.

Diagnostics The diagnostics for probit regression are different from those for OLS regression The diagnostics for probit models are similar to those for logit models For a discussion of model diagnostics for logistic regression see Hosmer and Lemeshow (2000 Chapter 5) References Hosmer D & Lemeshow S (2000) Applied Logistic.

The goodness of fit of the models was evaluated using the HosmerLemeshow statistic and their accuracy was assessed by calculating the nonparametric area (AUC) under the receiveroperating curve (ROC) with 95% confidence intervals (95%CI) [2324] The standard errors of the regression coefficients of the final model were calculated using 1000 bootstrap samples.

For those who aren’t already familiar with it logistic regression is a tool for making inferences and predictions in situations where the dependent variable is binary ie an indicator for an event that either happens or doesn’tFor quantitative analysis the outcomes to be predicted are coded as 0’s and 1’s while the predictor variables may have arbitrary values.

Hosmer & Lemeshow is also good If you want something brief and free (self plug alert) see my introduction to logistic regression but it may be too basic for your needs $\endgroup$ – Peter Flom Feb 12 ’14 at 1541 $\begingroup$ Ok thank for you´re quick answers i will try Agresti and see if it helps ) $\endgroup$ – user40116 Feb 12 ’14 at 1549 5 $\begingroup$ I don’t think.
