We introduce the Method of Simulated Moments (MSM) for estimating unknown parameters in dynamic models. The MSM is useful when there are empirical data related to the behavior of different entities and error terms do not follow any well-established distribution. Statistical moments such as mean and variance of empirical data can be matched against the moments of model-generated data in order to...

BACKGROUND HCV treatment uptake has drastically increased in HIV-HCV coinfected patients in France since direct-acting antiviral (DAA) treatment approval, resulting in HCV cure in 63% of all HIV-HCV patients by the end of 2015. We investigated the impact of scaling-up DAA on HCV prevalence in the whole HIV population and in various risk groups over the next 10 years in France using a transmissi...

BACKGROUND Three trials have demonstrated the prophylactic effect of male circumcision (MC) for HIV acquisition among heterosexuals, and MC interventions are underway throughout sub-Saharan Africa. Similar efforts for men who have sex with men (MSM) are stymied by the potential for circumcised MSM to acquire HIV easily through receptive sex and transmit easily through insertive sex. Existing wo...

We examine the performance of volatility models that incorporate features such as long (short) memory, regime-switching and multifractality along with two competing distributional assumptions of the error component, i.e. Normal vs Student-t. Our precise contribution is twofold. First, we introduce a new model to the family of Markov-Switching Multifractal models of asset returns (MSM), namely, ...

Despite constituting only about 1% of Ghana’s population, men who have sex with (MSM) carry a disproportionate burden HIV infections, 18% the population people living in country. Scholars associated infection rates among MSM existing structural factors (such as criminalization and stigma against MSM), individual-level without condom, transactional sex). Nonetheless, limited scholars consider in...

Characterization and modeling of metal-semiconductor-metal (MSM) GaAs diodes using to evaporate SiO₂ and Pd simultaneously as a mixture electrode (called M-MSM diodes) compared with similar to evaporate Pd as the electrode (called Pd-MSM diodes) were reported. The barrier height (φ(b)) and the Richardson constant (A*) were carried out for the thermionic-emission process to describe well the cur...

Despite consistent evidence, effective interventions and political declarations to reduce HIV infections among men who have sex with men (MSM), coverage of MSM programmes in sub-Saharan Africa (SSA) remains low. Punitive legal frameworks and hostile social circumstances and inadequate health systems further contribute to the high HIV burden among MSM in SSA. The authors use the Modified Social ...

OBJECTIVE To estimate the impact of late ART initiation on HIV transmission among men who have sex with men (MSM) in Mexico. METHODS An HIV transmission model was built to estimate the number of infections transmitted by HIV-infected men who have sex with men (MSM-HIV+) MSM-HIV+ in the short and long term. Sexual risk behavior data were estimated from a nationwide study of MSM. CD4+ counts at...

BACKGROUND We examined the effects and cost-effectiveness of 4 strategies of circumcision in a resource-rich setting (Australia) in a population of men who have sex with men (MSM). METHOD We created a dynamic mathematical transmission model and performed an economic analysis to estimate the costs, outcomes, and cost-effectiveness of different strategies, compared with those of the status quo....
