All results were tested against a null distribution generated using 1000 permutations and a false discovery rate threshold of 0.1%, with the minimum category size in all incidences set to five.
The map classifies arsenic concentrations into 10 categories, demarcated at the 10th, 20th, 40th, 60th, 80th, 90th, 95th, 99th and 99.9th percentiles of grid cell values, with the minimum category 0 4 parts per million (p.p.m).
They include coastal county maps, shaded to identify the minimum SSHS category of hurricane that will result in flooding, in each area of the county.
Patients at maximum-risk were approximately four times more likely to be institutionalised, twice as likely to be hospitalised and three times more likely to die at 1 year follow-up than those in the minimum-risk category.
At a minimum, categories of stakeholders add a level of structure to subsequent brainstorming and facilitate the identification of missing groups.
Also, the minimum sun exposure category in the questionnaire was up to 1 hr, and the rate of vitamin D synthesis per amount of sun exposure may decrease within this time period.
Hence it is argued that the minimum number of categories should be in the region of five to seven [ 2].
Streiner and Norman (1995)[ 4] argued that the minimum number of categories used by raters should be in the region of five to seven and that most people are unable to discriminate beyond seven categories.
In practice, the minimum headway for each category will be calculated as (see also Fig. 3): {t}_{f{m}_{L,R,M}}=frac{2*{l}_b+L}{V_{L,R,M}}+{t}_s (3) Open image in new window Fig. 3 Scheme for the calculation of the blocking time for double-track lines by [10].
The percentages, the maximal values and the minimum of 12 foods category frequencies in a week were intuitively showed in figure 2.
Because the number of flares in the past 12 months had been categorically documented (ie, 0, 1 to 2, or 3 or more episodes), the total number of flares was calculated by multiplying the number of patients in the 1 2 category by 1.5 (ie, the mean of the 1 2 category), and multiplying the number of patients in the ⩾3 category by 3 (ie, the minimum number of episodes in this category).
