Logistic Curve's Parameter Fitting under Missing Data
Ryutaro Matsumura, Daisuke Satoh (NTT) R2017-45
Abstract (in Japanese) (See Japanese page) 
(in English) The logistic difference equation can be solved by regression analysis to estimate parameters of logistic curve model with high accuracy. Usually, this approach uses constant step lengths. When there are missing data, parameter estimation is made so as to make step lengths equal in a limited data. The limiting of data area relinquishes parts of given data and the accuracy of parameter estimation can be worsened. This paper proposes solving logistic difference equation with variable step lengths by regression analysis and compare the result with constant step lengths in limited data. Real data analysis suggests one of the logistic difference equation with variable step lengths is effective.
