‘In a statistical sense, therefore, the multiplicative model signifies independent additive effects on a logarithmic scale.’
‘This may mean that loci affecting these traits combine in a way that is more nearly multiplicative than additive.’
‘Survival probabilities are multiplicative, so risk for a 5-day period was one minus the product of those five daily survival rate estimates, expressed as a percentage.’
‘This suggests that pollen viability corresponds more closely to the exponential quadratic model than to either the additive or the multiplicative model.’
‘For example, the linear model, multiplicative model, Poisson model, and negative binomial model have been used in modelling traffic accidents.’
‘These rates are greater than expected for additive or multiplicative effects of the single mutations.’
‘The multiplier of the hazard rate is the independent multiplicative effect of a variable on what a rate would have been otherwise.’
‘There are two types of ART algorithm, those employing additive and those employing multiplicative corrections.’
‘The number system which was used to express this numerical information was based on the decimal system and was both additive and multiplicative in nature.’
‘The genetics of period-altering alleles is perhaps best described by a multiplicative interaction, where each allele changes the period of the genetic background by a fixed percentage.’
‘Furthermore, we assumed that the various treatments had a multiplicative effect on all response variables.’
‘There are many objections to this hypothesis, but it may explain why the hazards of cardiovascular risk are synergistic or multiplicative rather than just additive.’
‘Factors with symmetrical multiplicative effects were identified in the formula.’
‘This is not a simple addition but is kind of multiplicative.’
‘Those who live abroad sometimes have a tendency to give a measly sum, say $50, thinking of the multiplicative factor of the exchange rate.’
‘Smoking and asthma had additive but not multiplicative effects on decline.’
‘The formula was designed to be multiplicative rather than additive because the panel theorized that, if any of these factors were negligible or not applicable at all, the risk would then be negligible.’
‘When the value of a geometric parameter in the model is zero, the multiplicative term becomes zero, and is therefore omitted.’
‘Consistent with our hypothesis, variables were created reflecting multiplicative interactions between harassment or abuse and personality characteristics.’
‘Previous analytical results have used branching processes with multiplicative selection to examine the probability that beneficial alleles are lost or fixed from very large populations.’
