I am currently working on the COVID data of a US state to predict the number of people affected per day and also the number of patients is hospitalized per day by developing the Fuzzy Mamdani Model using Matlab. Our team gathered the official data provided by the Department of Health of the state. We have taken into account the data from July 1st to November 30th (total 153 days).
Among the variables considered in the model, the most missing values are the number of(PCR positive patients and Antigen positive patients). Data of around 45 days are missing of these 2 variables of the total of 153 days. The good thing is the summation of PCR positive and Antigen positive patients are the total number of affected patients which is available for 153 days.
Now to fill the missing values of 45 days we are considering the average values of the Total number of affected, number of PCR positive, and the number of (153-45)=108 days and calculating the percentage ratio. After that fill up the missing 45 days data of PCR and Antigen positive based on this ratio.
Our team is expecting your criticism on the proposed method and at the same time your proposal for alternative method to fill the missing values. Thanks for your cooperation.
