A continuous mean-reverting time series can be represented by an Ornstein-Uhlenbeck stochastic differential equation: d x t = θ ( μ − x t) d t + σ d W t. Where θ is the rate of reversion to the mean, μ is the mean value of the process, σ is the variance of the process and W t is a Wiener Process or Brownian ...

Of course the original definitions of RDF (and thus equation 9a) did not account for the ‘[1 / (1 – .005161 * RE)]’ correction term. It was noted that Balling first pro-posed calculating the ratio of RDF/ADF20 and it is termed ‘Balling’s shorter formula’. honeypreet singh

WebMar 10, 2015 · The formula is: TDN = digestible NFE + digestible CF + digestible CP + (digestible EE x 2.25) Another method of calculating TDN is based on the percentage of acid detergent fiber (ADF) in the dry matter of the ration. Some types of fiber are more digestible than others, and the ADF is the least digestible portion.
