In stratallo: Optimum Sample Allocation in Stratified Sampling

stratallo

stratallo 2.2.1

• Changed the name of two parameters: a to A and a0 to A0 for several functions.
• Updated rnabox() so that it can perform both versions of the RNABOX algorithm, i.e.: step 1 handles one-sided upper bounds whilst step 2 handles one-sided lower bounds, or conversely, depending on the user preferences.
• Minor help and vignette updates, corrected typos from previous release.

stratallo 2.2.0

• Added new user functions: ran_round() and round_oric() for rounding of (non-integer) numbers.
• Renamed var_tst_si() function to var_st_tsi().
• Renamed var_tst() function to var_st().
• Added unit_cost variable into pop507, pop969 and pop10_mM datasets.
• Renamed allocation_summary() function to asummary().
• Added survey stratum cost parameter unit_costs to optcost() function.
• Added survey stratum cost parameter unit_costs to rna() function.
• Renamed parameter n to total_cost in rna() function.
• Renamed dopt() function to opt().
• Renamed nopt() function to optcost().
• In nopt() function, changed the name of two parameters: D to V and b to a0.
• Significantly updated help pages for most of the functions and the vignette.
• Minor change in the implementation of the rna(). Vector Ri of take-bound indices is now a logical vector instead of the integer vector.
• Removed h_get_which_violates() helper as it is not needed anymore
• Added new argument check_violations to rna() function which replaces h_get_which_violates() approach.
• Changed the parameter name from b to a0 in var_tst_si() function.
• Renamed rna_onesided() function to rna().

stratallo 2.1.1

• Minor typos corrections in manual pages.

stratallo 2.1.0

• Added new function allocation_summary() that summarizes the allocation.
• Added new function rnabox() to handle box-constraints case.
• Updated rna_onesided() so that it optionally returns take-Neyman, take-min, take-max set of strata indices.
• Renamed function rna_one_sided() to rna_onesided().
• Minor typos corrections in README, vignette.

stratallo 2.0.1

• Minor typos corrections in README, vignette, and help pages.

stratallo 2.0.0

• Added new user function nopt() for minimization of total sample size under constraints on variance and upper bounds on strata sample sizes.
• Re-factored rNa() into rna_one_sided() so that it also computes the allocation under optional lower bounds constraints.
• Renamed nopt() do dopt() to reflect the fact that it minimizes variance function D.

stratallo 0.1.0

• First release.
