There are two main estimators for such models: unconditional maximum likelihood and conditional maximum likelihood. Judged on asymptotic properties, the conditional estimator is superior. However, the unconditional estimator holds several practical advantages, and therefore I sought to determine whether its use could be justified on the basis of finite-sample properties. In a series of Monte Carlo experiments for T is greater than 20, I found a negligible amount of bias in both estimators when T is greater than and equal to 16, suggesting that a researcher can safely use either estimator under such conditions. When T is less than 16, the conditional estimator continued to have a very small amount of bias, but the unconditional estimator developed more bias as T decreased."},"dsDescriptionDate":{"typeName":"dsDescriptionDate","multiple":false,"typeClass":"primitive","value":"2001"}}]},{"typeName":"publication","multiple":true,"typeClass":"compound","value":[{"publicationCitation":{"typeName":"publicationCitation","multiple":false,"typeClass":"primitive","value":"Ethan Katz. 2001. \" Bias in Conditional and Unconditional Fixed Effects Logit Estimation.\"  Political Analysis, 9(4), 379-384. <a href= \"http://polmeth.wustl.edu/polanalysis/vol/9/WV008-KATZ.pdf\" target= \"_new\">article available here</a>"}}]},{"typeName":"producer","multiple":true,"typeClass":"compound","value":[{"producerName":{"typeName":"producerName","multiple":false,"typeClass":"primitive","value":"Political Analysis"},"producerURL":{"typeName":"producerURL","multiple":false,"typeClass":"primitive","value":"http://pan.oxfordjournals.org/"}}]},{"typeName":"productionDate","multiple":false,"typeClass":"primitive","value":"2001"},{"typeName":"distributor","multiple":true,"typeClass":"compound","value":[{"distributorName":{"typeName":"distributorName","multiple":false,"typeClass":"primitive","value":"Murray Research Archive"},"distributorURL":{"typeName":"distributorURL","multiple":false,"typeClass":"primitive","value":"http://www.murray.harvard.edu"},"distributorLogoURL":{"typeName":"distributorLogoURL","multiple":false,"typeClass":"primitive","value":"http://murray.harvard.edu/files/murray/banner146x48.png"}}]},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2010"}]}},"files":[{"description":"","label":"KATZWEB.ZIP","restricted":false,"version":1,"datasetVersionId":43986,"categories":["2.
