In discrete choice models the marginal effect of a variable of interest that is interacted with another variable differs from the marginal effect of a variable that is not interacted with any variable. The magnitude of the interaction effect is also not equal to the marginal effect of the...

This paper compares direrent versions of the simulated counterparts of the Wald test, the score test, and the likelihood ratio test in the multiperiod multinomial probit model. Monte Carlo experiments show that the simple form of the simulated likelihood ratio test delivers the most favorable...

We further examine the interaction effect in nonlinear models that has recently been discussed by Ai and Norton (2003). Statistical tests about partial effects and interaction terms are not necessarily informative in the context of the estimated model. We suggest more useful ways that do not...

This study examined the legal income ex-inmates earned in 1986. The mean income was $5496.70. The median Income was $2900.00. Income had a positive skew of 1.62172. Our research hypothesis was that four quarters of employment in 1986 was the biggest factor affecting income (r=.71, p.05). Recent...

The research examined the impact of social media; social networking theory, word of mouth¸ feedback loop, and creditability content on the consumer buying behavior in Pakistan. The structured questionnaire was shared using convenience sampling between 650-700 participants. However, received 392...

We develop a general model for finding the optimal penal strategy based on the behavioral traits of the offenders. We focus on how the discount rate (level of time discounting) affects criminal propensity on the individual level, and how the aggregation of these effects influences criminal...

This article aims to remedy a common misinterpretation of insignificant coefficient estimates and presents a method to find hidden information in insignificant effects. I first discuss possible reasons for insignificant effects. I then use two distinct research areas as case studies: (1) how...

This paper analyzes the 5-, 14- and 21-day cumulative positivity rate vis-à-vis the COVID-19 deceased rate of each time period for the first four months of COVID-19 from April 2020 to September 2020 in New Delhi, India with the intention of getting insight into the relationship between the two...
