In Leontief case (fixed-proportion aggregate), the weights do not change in response to relative price changes, while they do in other cases, depending on the elasticity of substitutability and transformation.
The two-stage analysis will use linear regression for continuous outcomes and logistic regression for proportions, aggregated across studies by random effects inverse variance methods.
Linear regression was used to investigate the association between trusts' hospital-wide SMRs and avoidable death proportions (aggregated for the trust) rather than correlation because the correlation is subject to downward biased estimates if there is random measurement error in one of the variables.
Pooled estimates were calculated as odds ratios [OR; the ratios of the proportion of aggregate containing/normal (or TUNEL positive/TUNEL negative) nuclei in different experimental conditions] with 95% confidence intervals, as described previously.
We present simple frequencies for indicators measured at hospital level and use the median of hospital-specific proportions or simple aggregate proportions as a point estimate for indicators based on evaluation of multiple cases from each survey.
In excess of 200 aggregates were measured for each sample and the proportion of aggregates of different sizes determined.
Furthermore, soil microbial groups were highly correlated with soil SOC (P < 0.001), C/N ratio (P < 0.001), pH (P < 0.01), total nitrogen (P < 0.01), and the proportion of aggregates with a >0.25 mm diameter (P < 0.05).
The mobilization rate of aged binder was calculated on the basis of surface area proportion of aggregates with different size.
They are mainly composed of lime with differing in the type and proportion of aggregates used, including crushed carbonate rocks (limestone), gypsum, and siliceous sand.
After an incubation period of 28 days, the increase in G. granulatus population density reduced the proportion of aggregates between 1.00‐2.00 mm (y = 236.16 − 1.4921x, P < 0.05).
This can be made by replacing some proportion of aggregates with another material having a lower thermal conductivity and heat capacity in concrete mix design.
