Theory and Observation in Family Epidemics of the Common Cold

Pneumococcal carriage in children during their first two years: important role of family exposure

“…[15][16][17][18] For transmission within families several factors such as sleeping arrangements, poor ventilation or level of general hygiene were studied as early as 40 years ago, but only crowding was shown to be associated with a high prevalence of Pnc carriage. 7 Among the Australian aborigines overcrowding in homes was suggested as the main factor explaining both the high carriage prevalence and the acquisition of pneumococcal infections very early in life.…”

On a Family of Distributions With Argument Between 0 and 1 Obtained by Transformation of the Gamma and Derived Compound Distributions

“…The GIBD was fitted to the other sets of data reported in Gritfiths, i.e. Lidwell and Somerville (1951) and Heasman and Reid (1961), giving similar results to the BBD.…”

On Estimating the Parameters of an Extended Form of Logarithmic Series Distribution

“…one can obtain maximum likelihood estimates of the parameters θ 1 and θ 2 of the ELSD. For numerical illustration, we considered two data sets where the first data sets is from a zero- truncated data set on the counts of the number of European red mites on apple leaves, used earlier by Jani and Shah (1979) and the second sets is on family epidemics of common colds obtained by Heasman and Reid (1961). We fitted both the LSD and the ELSD to the data set and the results obtained along with the corresponding values of the expected frequencies, chi-square values, degrees of freedom (d.f.)…”
