I have sample size of 215 with 10 of them having disease positive and I have about 20 covariables that I want to examine. Can I do univariate logistic Regression for each and those with p- value more than 0.1 are to be included in Firth logistic regression ?
how can I interpret the results in SPSS ?
when I do this that appears
Conf. Interval Type Wald
Conf. Interval Level (%) 95
Estimation Method Firth penalized maximum likelihood
Output Dataset –NA–
Likelihood Ratio Test 38.0566
Degrees of Freedom 11
Significance 7.65335733629025e-05
Number of Complete Cases 176
Cases with Missing Data 39
Number of Iterations 26
Convergence Status Converged
Last Log Likelihood Change 6.3948846218409e-14
Maximum Last Beta Change 5.36667170504665e-06
what is the significance = 7.65335733629025e-05 , last log likelihood and maximum ones ??
