We derive fixed effects estimators of parameters and average partial effects in (possibly dynamic) nonlinear panel data models with individual and time effects. They cover logit, probit, ordered probit, Poisson and Tobit models that are important for many empirical applications in micro and ...

Vertebrates harbour diverse communities of symbiotic gut microbes. Host diet is known to alter microbiota composition, implying that dietary treatments might alleviate diseases arising from altered microbial composition (‘dysbiosis’). However, it remai
probitfe fits a probit fixed-effects estimator that can include individual and/or time effects, and account for both the bias arising from the inclusion of individual fixed-effects and/or the bias arising from the inclusion of time fixed-effects. probitfe with the nocorrection option does not ...
Fixed-effects regressions of perceived detection risk on criminal experiences and interactions between criminal experiences and measures of criminal propensity (risk-affinity, impulsivity) are estimated. Results Analyses support learning models for the formation and change of risk perceptions, but individual ...
the day39; the analysis of this behavior therefore also included sex (fitted as a two-level categorical variable: female vs. male) and time of day (hours from sunrise; fitted as a continuous variable; mean centered and expressed in standard deviation units) as two additional fixed effects. ...
Methods Compared to a cocaine reference dose, nicotine dose and timeout (TO) value were varied in eight rhesus monkeys responding for intravenous (i.v.) nicotine on varying fixed-ratio (FR) schedules of reinforcement.The aversive effects of nicotine were evaluated in four animals choosing between...
To avoid breaking any rules, Player 2 must buy an item (Rule 2), and they can only buy one item from the store (Rule 3). The software environment counted an error every time a player broke a rule. The session ended when the 10-minute game timer reached zero, or all players ...
000 early exercises in non-tradable putable bonds over a time period of 13 years indicates that Individual Investors (i) act very heterogeneously, (ii) behave as if they face significant individual transaction and decision costs, (iii) react sluggishly, and that (iv) exogenous effects such as ...
a time when children frequently talk out loud to themselves while engaged in a range of activities. As children get older, their private speech becomes increasingly more difficult to understand because it is both quieter (whispering and muttering) and more abbreviated and condensed (occasional words...
