Abstract:
1. A method for determining a significance of a social economic variable of vulnerability within the context of an urban heat island effect, with respect to urban extreme heat event mortalities comprising: (a) calculating, by a computer, a centroid of each plurality of block group; (b) assigning, by the computer, measures of socio-economic vulnerability, decedents, and stratified temperature to the centroid; (c) calculating, by the computer, a weighted mean center of extreme heat event mortalities; (d) calculating, by the computer, weighted mean centers of socio-economic variables of vulnerability using the respective centroids as points; (e) calculating, by the computer, a weighted mean center of stratified temperatures using the respective centroids as points; (f) calculating, by the computer, an extreme heat event standard deviation ellipse of the extreme heat event mortalities, using the weighted mean center as the origin; (g) calculating, by the computer, an eccentricity value for the extreme heat event standard deviation ellipse of the extreme heat event mortalities; (h) calculating, by the computer, a respective standard deviation ellipse for each socio-economic variable; (i) calculating, by the computer, a respective standard deviation ellipse for each stratified temperature value using the corresponding weighted mean center; (j) using, by the computer, T-test and F-test techniques to determine spatial similarity between the respective extreme heat event standard deviation ellipses and the respective standard deviation ellipses for each socio-economic variable and for each stratified temperature value; (k) calculating, by the computer, an extreme heat event mortality concentration within each standard deviation ellipse for each socio-economic variable and for each respective stratified temperature value shown to be spatially similar as a number of extreme heat event mortalities coincident within the standard deviation ellipse divided by the area of the standard deviation ellipse; (l) calculating, by the computer, an eccentricity for each respective socio-economic variable and for each respective stratified temperature value identified to be spatially similar; (m) marking, by the computer, each identified spatially similar socio-economic variable and stratified temperature value significant where the extreme heat event mortality concentration is above a predetermined threshold and the eccentricity value is within a predetermined range of the eccentricity of the extreme heat event mortality; and (n) providing, by the computer, an output of the significant socio-economic variables and stratified temperature values.
