RigStatisticsCalculator::mobileVolumeWeightedMean() accumulated into a sum
from an out-parameter that callees were not required to write. Every
implementation of the per time step overload has early-return paths that
leave the value untouched, as does RigWeightedMeanCalc::weightedMeanOverCells,
so indeterminate stack memory could be summed and presented in the UI.
Return std::optional<double> from the computation layer instead of using an
out-parameter, making "value not available" explicit and impossible to ignore:
- RigWeightedMeanCalc::weightedMeanOverCells
- RigStatisticsCalculator::mobileVolumeWeightedMean and all overrides
Time steps without a computable mean no longer contribute to the accumulated
sum, and are excluded from the divisor. Previously they would either add
garbage or, with a naive zero initialisation, bias the average towards zero.
RigStatisticsDataCache keeps the existing HUGE_VAL marker on its public API
via value_or(), so behaviour seen by RigHistogramData and the overlay info
is unchanged apart from the fix.
Also:
- Set m_isVolumeWeightedMeanCalculated in the per time step cache, which was
never assigned, so the cached value was recomputed on every call.
- Remove a duplicated ensureKnownResultLoaded() call in
RigEclipseNativeVisibleCellsStatCalc.
Fixes#14766
The single-pass sum-of-squares formula subtracts two large and nearly equal numbers. Where a result such as PORO is identical or near-identical across the realizations, the true variance is below the rounding noise floor, the radicand turns negative and sqrt() returns NaN.
Compute the deviation in two passes instead, centering on the exact mean. This also removes the loss of significance the old formula had for values with a large common offset.
Min, max, range, mean and deviation all report HUGE_VAL when the input holds no valid values, but the sum reported the zero it was accumulated from. A caller testing the result with isValidNumber would accept that zero as real data.
Add BinningMode (Linear/Logarithmic) and OutOfRangeHandling (Exclude/Include in
Boundary Bins) to RigHistogramCalculator, with defaulted constructor arguments so
existing callers are unaffected. All four histogram plot data sources get shared
options for binning mode and an optional user-defined bin range through new PDM
fields on RimHistogramDataSource.
The grid statistics data source computes non-default histograms through a new
non-caching RigStatisticsDataCache::computeHistogram() pass-through, leaving the
cached statistics used by the 3D overlay and the P10/P90/mean annotation lines
untouched.
Selecting logarithmic binning enables logarithmic scale on the plot X axis once,
via a new signal handled by RimHistogramCurve.
Also fix the bin index computation to use uniform bins of width range/nBins,
consistent with calculatePercentil() and the bin edges drawn by the plots. The
previous divisor (nBins - 1) shifted counts by up to one bin width relative to
the drawn bars and slightly biased histogram-based percentile estimates.
Migrate all assert macros in ApplicationLibCode to CAF_ASSERT and remove every
use of cvfAssert.h.
CVF_ASSERT is replaced one to one. CVF_TIGHT_ASSERT is also replaced by
CAF_ASSERT, which is semantically exact: CVF_ENABLE_TIGHT_ASSERTS is 1 only
under _DEBUG, and that is what CAF_ASSERT now does. The two CVF_FAIL_MSG sites
become CAF_ASSERT( false && "message" ), preserving the message with the idiom
already used elsewhere in the code base.
Counts before and after: CVF_ASSERT 1044 to 0, CVF_TIGHT_ASSERT 66 to 0,
CVF_FAIL_MSG 2 to 0, cvfAssert.h references 154 to 0.
Include handling: files that included cvfAssert.h directly now include
cafAssert.h instead, includes left dead by the migration are removed, and files
that were relying on cvfAssert.h transitively get an explicit cafAssert.h. Files
that reach cafAssert.h through another caf header are left unchanged; a missing
include here is a compile error, not a silently disabled assert.
ResultStatisticsCache links only LibCore and therefore had no path to
cafAssert.h. Add the cafPdmCore directory as a private include path rather than
linking the library, since cafAssert.h is header only.
Note that this stops these asserts from firing in Release and RelWithDebInfo,
where CVF_ASSERT was previously active.
When fewer than 9 valid realizations exist at a time step, the linear
interpolation percentile formula has no valid result for P10 and P90.
Previously HUGE_VAL (inf) was returned. Now clamp to min/max of the
available sorted values instead, avoiding inf in plotted curves.
Replaced all references to RiaStatisticsTools with RigStatisticsTools across the codebase, including header includes, static method calls, and test files. Updated CMake configuration to remove RiaStatisticsTools and add RigStatisticsTools. Renamed and updated related unit tests. No changes to logic or algorithms; this is a namespace and organizational refactor for consistency. Also added ApplicationLibCode include directories as PRIVATE to relevant targets.
* Refactor and extend percentile calculation utilities
Refactored percentile and quantile calculation logic for improved flexibility and maintainability. Added helper functions for quantile/percentile validation, introduced a new vector-based calculatePercentiles method, and updated calculateStatisticsCurves to use it. Refactored nearest-rank and interpolated percentile methods to accept percentiles as vectors and improved parameter validation. Enhanced documentation throughout and updated function signatures in the header for clarity.
* Add single case well target results into correct time step
* Speed up unique value calculations by providing unique values directly to statistics cache
* Switch to selected time step in view
Statistics can be computed in two ways, precise using all available cell values and fast based on a histogram. A flag indicates if the P10/P90 values are calculated. Check this flag before assigning values using the fast histogram method.
* Fwk: Avoid use of include_directories
* Remove target_include_directories from Commands
* Refactor cmake includes
- Avoid using include_directories, and use target_include_directories.
- Use add_subdirectory directly from main cmakefile, do not use in ApplicationLibCode.
- Set default frequency enum to relative frequency [%]
- Set current view selected in filter by 3D view visibility by default
- Add labels for statistics data
- Add UI to change number of bins in histogram
- Add control of font size of axis values and axis titles
* Use horizontalAdvance
* Remove unused code
* Hide some warnings from Qt code
* Remove message for _SILENCE_TR1_NAMESPACE_DEPRECATION_WARNING
* Use CMP0077 NEW
* Move roff libraries to folder Thirdparty
* avoid operator()==
* Remove cmake_minimum_required and set version to 3.15
