Introduction Dengue is endemic in Singapore, with epidemics of increasing magnitude occurring on a six-year cycle in 1986/7, 1992, 1998, 2004/5, 2007 and 2013. The incidence per 100,000 population ranged from 87.2 to 105.6 in 2009-20121, and surged to 410.6 in 2013. The mean weekly number of dengue cases over a five-year period provides an indication of the baseline level. We illustrate an adju...

We conducted research for planning the launch of a satellite television product, leading to a prelaunch forecast of subscriptions of satellite television over a five-year horizon. The forecast was based on the Bass model. We derived parameters of the model in part from stated-intentions data from potential consumers and in part by guessing by analogy. The 1992 forecast of the adoption and diffu...

On a well defined non-diabetic amputation group with vascular insufficiency consisting of 10,191 amputations during the period 1982 to 1992 the Standard Mortality Rate (SMR) and the long term survival (Kaplan-Meyer) were analysed. The SMR for the total group was 8.6 (8.4-8.9) times the expected mortality the first year after amputation, decreasing to 3.2 (3.3-3.4) the second year. SMR in relati...
