The univariate case, in which only one proportion or s share per establishment is analysed and for which papers by Papke and Wooldridge ([1996], for cross-sectional and [2008] for panel data) represent crucial contributions to the literature, will not be discussed in detail.
Aminoterminal propeptides are cleaved from procollagens in a one to one proportion and thus reflect the synthesis of collagen.
How large should the difference be between the proportion in one group and the proportion in the other group (P1-P2) for it to be clinically significant?
In fact, when considering pairwise comparisons for the response item "tuberculin skin test," with a sample size of 100 in two groups, a two-group chi-square test with a 0.017 two-sided significance level would have 80% power to detect a difference between a 65% proportion in one group and a 85% proportion in the other group.
The general efficiency of the entire system is defined by a relationship between the numbers of events which are handled by sensors in one WSN in proportion to other WSNs regarding some parameters such as end-to-end delay, packet loss, throughput, and path complexity.
In one generation the proportion of children regularly playing in wild places in the UK has fallen from more than half to fewer than one in 10.
In one study, the proportion of colorectal cancer patients experiencing distress increased from 30% at baseline as measured by the Brief Symptom Inventory (BSI-18) to 37% at the second assessment point (Jefford et al, 2011).
To identify amino acids that deviated from the overall pattern in particular species pairs, the residual (difference between the observed proportion of substitutions in one direction and the proportion predicted by the logistic regression model) was calculated for each amino acid pair in each species pair and then averaged across the 19 pairs involving each amino acid.
We calculated relative risks with 95% confidence intervals, using the ratio of the proportion of each outcome in one group to the proportion in the comparator group.
Shechtman and his coworkers mixed aluminum and manganese in a roughly six-to-one proportion and heated the mixture until it melted.
