The phrase "an assumption of zero" is correct and usable in written English.
It can be used in contexts involving statistics, mathematics, or hypothesis testing where a value of zero is being considered as a baseline or starting point.
Example: "In our analysis, we made an assumption of zero for the initial value to simplify the calculations."
Alternatives: "a zero assumption" or "a null hypothesis".
Equation 3 is based on an assumption of zero heat loss through the insulation layer.
This evaluation approach is based on an assumption of zero moving costs, making the value an upper limit for the individual's WTP.9 In this study we only conduct the first step and, therefore, estimate the monetary values using the hedonic price function.
Under an assumption of zero genotyping error (pedigree 1), parental pairs were assigned to 62% of the offspring (i.e. 71 individuals in total), with no assignment possible for 37%, and 0.8% (i.e. one individual) having ambiguous assignment (i.e. more than one parental pair getting the highest likelihood score).
An assumption of zero background rate is made in estimating the aftershock activity by fitting ETAS model to the complete sequence of earthquakes, and thus the estimate of (mu (t)) obtained by this method could be biased.
There was a shape that resembled a head, plus four distinct parts that roughly corresponded with two arms and two legs, further articulated by an assumption of ten fingers and ten toes, presently wriggling.
Along with an assumption of six years intervention, prevention programmes were associated with cost-saving compared with the control group, especially in the population aged 25 years.
With an assumption of two EBP runs per day and 90 s hands-on time/specimen, there was an 85 % reduction of time to reportable results compared to culture.
Demographic values were obtained through a molecular clock scalar calibration to obtain parameters per base pair and per generation, taking as reference Brower's 2.3% divergence in mtDNA per million years estimated for insects [ 71] and with an assumption of four generations per year (Table 4).
In fact requirements of Jensen concavity of mean and its symmetry were taken just to provide an assumption of these two results to be satisfied.
With the site's increasing global adoption rate that would roughly translate to a maximum potential flow of approximately $900 million (based on an assumption of 900 million total users of the site).
In the present study, we show that the apparent discrepancy between titration data sets results in large part from the widespread use of an erroneous assumption of zero specific net proton surface charge at the onset of titration.
