Maximization of the loglikelihood of the mixed SDE with Normal distribution of the random effects
\(dXj(t)= (\alpha_j- \beta_j Xj(t))dt + \sigma a(Xj(t)) dWj(t)\), done with likelihoodNormal
EstParamNormal(U, V, K, random, estim.fix, fixed = 0)
matrix of M sufficient statistics U
list of the M sufficient statistics matrix V
number of times of observations
random effects in the drift: 1 if one additive random effect, 2 if one multiplicative random effect or c(1,2) if 2 random effects.
1 if the fixed parameter is estimated, when random 1 or 2 , 0 otherwise
value of the fixed parameter if known (not estimated)
estimated value of the mean
estimated value of the variance
BIC indicator
