The highest outdoor concentrations (8-hour mean equal to 36.9 · 103 pandicles/cm38.8d 38.8 · 103 particles/cm3) were measured at two schools, both affected by heavy traffic.
The highest mean indoor concentrations were observed in a small carpet-covered library and a teachers' office (8-hour mean equal to 52.6 · 103 pandicles/cm3 and 50.2 · 103 parespectively respectively), at the same school unit.
To ensure adequate comparison of the values for each variable, each one was centered and scaled to mean equal to zero and standard deviation equal to 1.0.
I mean, equal to winning the lottery kinda joy.
aIndices generated from standardized (mean equal to zero and standard deviation equal to one) values of individual items all scored in the positive direction.
The additive genetic correlation was moderately favorable with marginal posterior mean equal to 0.37 and 95% central posterior credibility interval ranging between 0.11 and 0.61.
Hyper-prior lognormal distributions were set as: mean equal to 6, 6, −4 and 8; SD equal to 2, 2, 0.25 and 2; hyper-prior of mean equal to 0, 0, 0 and 0; hyper-prior of SD equal to 0.5, 0.5, 0.5 and 0.5 for N0, N1, μ and Ta, respectively.
The scaling factor is the amount of scaling applied to the values for each array to make its intensity mean equal to a pre-specified value, which is called Target intensity value (TGT); the default value is usually 100.
Monte Carlo simulations were carried out with sample size of 10 000 cells with normal distributions of initial concentrations (mean equal to the initial concentration in the Albeck model, and variance equal to 40% of the mean initial concentration).
To estimate the uncertainty in annual values, we assumed independence in the errors of half-hourly gap-filled estimates and a normal distribution with a mean equal to the corresponding gap-filling estimate and a standard deviation of σi.
PDFmodel uncertainty is assumed to be a Gaussian with mean equal to zero and standard deviation equal to 10% of the ηtide, as model validation45 showed normalized mean square errors around 10%.
