Using E-Surge for individual covariates

[Jocelyn]

Sorry,
Well to explain better, ESURGE run well but the survival and resighting probabilities (the estimate parameters) are not presented!
Only the Beta parameters are obtained from the results
Thanks

This is normal. There is two much parameter to compute.
You must do it from beta :

see the "Add-in: fixed effects with individual covariates" from the help menu

Below is a code example of the computation of the survival and CI for one individual
( this is done in Matlab but it can also be easily done with R )
%% Matrix of Variance-Covariance of mathematical parameters 1 to 4
A=[ 0.00472105 6.37793E-05 0.000948974 -0.001084087; ...

-0.001084087 0.00821715 -0.00641768 0.020066974]
%% Vector of Weigth^0, Weigth^1, Weigth^2, Weigth^3 for individual 1 with history 10000000
w=[1 -0.8305 -0.2190 0.0969]
%% Vector of mathematical parameters
beta=[0.545722383; -0.003197205; -0.279027297; 0.250431933];
%% Computation of survival
expbeta=exp(w*beta);
phi=expbeta/(1+expbeta)
%% Computation of variance for survival
phi1unmoinsphi=phi*(1-phi);
U=phi1unmoinsphi1*(w)';
varphi=U'*A*U
%% Computation of CI for survival
CIphi=[ phi1-1.96*sqrt(varphi1), phi1+1.96*sqrt(varphi1)]
