Workflow Damping ratio (2)

Thumb
The Damping ratio Workflow provides an environment to calculate the damping ratio of several matrices and plot them. The damping ratio can be considered as a measure of the intrinsic resilience of the population, describing how quickly transient dynamics decay following disturbance or perturbation regardless of population structure, the larger the p, the quicker the population converges. ============================================================= This workflow requires an instance of Rse...

Thumb
The Parametric Bootstrap or Resample a projection matrix Workflow provides an environment to resample a projection matrix using a multinomial distribution for transitions and a log normal distribution for fertilities (Stubben, Milligan, and Nantel. 2011). The resample is based on number of plants surveyed. The projection matrix A is first split into separate transition and fertility matrices. Dead fates are added to the transition matrix and the columns are then sampled from a Multinomial dis...

Pooled_matrix_file or weighted main Matrix - what popbio (R package) calls pooled matrix (to see more details: Horvitz, Schemske and Caswell 1997; Horvitz, and Schemske 1995). This is a matrix in a .txt format, all decimal numbers in each matrix must be indicated by dots e.g.: 0.578.To understand how to calculate a pooled matrix or a weighted main Matrix, please see: Choice of a reference matrix (pag: 253, in Horvitz, Schemske and Caswell 1997). This list of matrices will be used to perf...
