It should be as simple as using the "sample" keyword in the
boost::accumulators namespace, like:
using namespace boost::accumulators;
accumulator_set< int, featurestag::weighted_sum > acc( sample = 42 )
Thanks Eric. Indeed, it works !
But my problem was actually independent of this.
I am using more features, and it seems that we can't use more than 4 tagged
arguments !!!
using namespace std;
using namespace boost::accumulators;
typedef accumulator_set, double> AccType1;
typedef accumulator_set,
double> AccType2;
typedef accumulator_set, double> AccType3;
double probs[] = {0.01,0.05, 0.25, 0.33, 0.5, 0.67, 0.75, 0.95, 0.99};
vector<double> q_probs(probs, probs + sizeof(probs) / sizeof(double));
AccType1 acc1(tag::weighted_density::cache_size = 10,
tag::weighted_density::num_bins = 10,
tag::weighted_extended_p_square::probabilities = q_probs,
tag::weighted_p_square_cumulative_distribution::num_cells =
10);
// compiles (4 tagged arguments)
// AccType1 acc2(sample = 42, tag::weighted_density::cache_size = 10,
// tag::weighted_density::num_bins = 10,
// tag::weighted_extended_p_square::probabilities =
q_probs,
//
tag::weighted_p_square_cumulative_distribution::num_cells = 10);
// Error : does not compile (5 tagged arguments)
AccType2 acc3(sample = 42, tag::weighted_density::cache_size = 10,
tag::weighted_density::num_bins = 10,
tag::weighted_p_square_cumulative_distribution::num_cells =
10);
// compiles (4 tagged arguments)
AccType3 acc4(sample = 42, tag::weighted_density::cache_size = 10,
tag::weighted_density::num_bins = 10,
tag::weighted_extended_p_square::probabilities = q_probs);
// compiles (4 tagged arguments)
I wanted acc2, so I thought my syntax using the "sample" keyword was wrong
but it was not, as acc3 and acc4 do compile.
Is that a bug ?
