The phrase "assuming a frequency of" is correct and usable in written English.
It can be used in contexts where you are establishing a baseline or condition related to frequency, often in scientific or technical discussions.
Example: "The results were calculated assuming a frequency of 60 Hz for the electrical system."
Alternatives: "given a frequency of" or "considering a frequency of".
Sample dimension was then estimated, assuming a frequency of the predisposing allele of 0.15, a disease prevalence of 0.4 (prevalence of asthma in the allergic population is ≥40%) [21], a genotype relative risk of 1.7 (for both the homozygote and heterozygote), and a marker frequency of 0.2 (taken from Affymetrix product description).
Assuming a frequency of mutational events similar to that seen in AML patients (7%), we would expect to detect 4.34 mutations among the 62 ALL patients screened.
We determined a priori that our study with 400 sporadic CRC cases and 400 matched controls would enable us to detect an OR of 2.0 for 9A/6A heterozygous individuals (assuming a frequency of 0.15 in controls) and an OR of 3.0 for 6A/6A homozygous individuals (assuming a frequency of 0.0175 in controls) with 80% power (two-sided test, alpha level = 5%).
Sample size estimates were based on calculations to detect an odds ratio (OR) of 3, assuming a frequency of single exposure of 25% among controls and 40% among patients, with a power of 80% and a significance level of 5%.
Assuming a frequency of 1.1% of the deleterious allele in the Fleckvieh population, equal use of all bulls and ~1,000,000 annual births, one would expect 121 affected calves per year.
The Dutch (N=188) and Scottish (N=288) studies individually had a power of 95.7 and 99.5% to detect a HR of 2, assuming a frequency of p53 abnormalities at 50 and 40% censoring.
For both the macrocell and the femtocell we assume a frequency of 2.6 GHz as defined in the LTE standard.
The dose of PCB3 exposure was estimated using the following equation For these experiments, we assumed a frequency of breathing (f) of 94 breaths/min, tidal volume (Vt) of 1.5 mL/breath, and uptake from the lungs of 99.89%.
Results also confirm that the interaction tests based on Equation (1) are robust to genotype frequency misspecification: data analysis assuming a frequency distribution of 0.01, 0.18, 0.81 as well as 0.25, 0.50, 0.25 gave exactly the same interaction error rate as when the correct genotype frequencies of 0.09, 0.42, and 0.49 were used.
The waveform was assembled assuming a frequency modulation index m f of 40, and the fundamental frequency and amplitude were fixed at 50.02 Hz and 5.4 A, respectively.
Considering the spectral spreading of the waves, we assume a frequency resolution of a few hundred hertz.
