Sinusoidal exponential distribution for modeling elevated creatinine kinase level as the initial presentation of Covid-19

Abstract This paper is devoted to deriving a new lifetime distribution based on a sine function to model different initial symptoms of Covid-19 patients that initially present as muscle weakness with increased Creatinine Kinase (CK), without fever or respiratory symptoms. The new distribution is cal...
