For each subject, the following descriptive statistics were computed in Microsoft Excel (Office 2000, Microsoft corp .: the mean (x ¯ ), the minimum (MIN) and maximum (MAX) rates, the maximum to minimum rate ratio (MAX/MIN), and the coefficient of variation in rate values (expressed as a percentage (%CV)).
Each window includes its maximum Incidence Rate Ratio (IRR) and its corresponding time of the day.
Under this assumption, the model predicts a decrease in precipitation rate that is symmetric around a maximum rate at an ion ratio equal to the stoichiometric ratio of solid phase (1 for calcium carbonate).
The fresh catalyst gives a maximum rate with an H2 CO CO2 ratio of 70 28 2, whereas the deactivated catalyst gives maximum rates if a synthesis gas with ratio 70 0 30 is used.
The correlations between CD with all other variables showed a maximum change of 0.03, while the disease rate ratios showed a maximum change of 0.04.
The maximum likelihood procedures evaluate heterogeneous rate ratios among sites by applying different models of codon evolution.
Tabulation of individual records into person years tables and Poisson regression analyses of person years at risk, with calculation of maximum likelihood estimates of incidence rate ratios (IRR) and likelihood ratio tests were performed by means of the EPICURE programme package (Preston et al, 1996).
The best-fitting baseline weather model, after univariate inclusion of each weather variable, included daily maximum relative humidity (rate ratio (RR) 1.08, 95% CI 1.04 1.13) and daily minimum air temperature (RR 0.87, 95% CI 0.78 0.97) each at a lag of three days, and unlagged daily mean solar radiation (RR 1.07, 95% CI 1.01 1.13).
We isolated usp and cox1 in several species of Drosophilidae, Tenebrionidae and Blattaria and estimated non-synonymous/synonymous rate ratios using maximum-likelihood methods and codon-based substitution models.
To calculate risk factors for recent DENV infection, incidence rate ratios (IRR) were obtained as conditional maximum-likelihood estimates of the rate ratio, with mid-P exact test, 95% CIs, and p values.
