i have the following regression equation
Log(total deaths per million) = -3.882 + 0.934Log(total cases per million) – 0.033(gdp per capita) + 0.014(aged 70 or older) - 0.050(hospital beds per thousand) + 0.011(human development index)
How would I interpret the effect of aged 70 years or older, which is the percent of the population aged 70 or older
