Full Changelog: v0.3.3...v0.3.4

Version 0.3.3

Features

• Added Xbar and S chart utility plot_xbs()
• Added fit_polyridge() to return fitted model based on polynomial ridge regression. Useful for cross-validation of polyridge hyperparameters, and another metamodel option!

Documentation

• Significant improvements to transform documentation, including tran_rename, tran_mutate, tran_filter, tran_select, tran_sample, tran_summarize, and associated helper functions

Fixes

• Removed a use of np.int

Version 0.3.2 (Hotfix)

Fixes

• add psdr subpackages to setup.py to fix ModuleNotFound errors

Version 0.3.1

Breaking changes

• deprecate tf_transmute()
• rename Marginal.l() to Marginal.d(); this is a density, not a likelihood
• rename marg_named() to marg_fit(); that name is confusing now that we also have marg_mom()
• change argument order for marg_fit() to make consistent with marg_mom()
• rename colmin -> min, colmax -> max, colsum -> sum

Features

• add random variable sample to marginals Marginal.r(n)
• add frozen location parameter option to marg_mom() and marg_fit(); enables access to 2-parameter lognormal and 2-parameter Weibull distributions
• make marginal summary output more readable by reporting standard moments, rather than distribution parameters
• add autoplot dispatch from eval_contour() output
• add linspace() and logspace() helper functions
• add thermal-radiation channel model based on Andrew Banko's thesis; verify implementation against existing data
• add tran_iocorr() to compute input/output correlations; autoplot dispatch for useful EMA tool (correlation tileplot)
• add mean_lo|up() and pr_lo|up() helper summary functions to compute lower and upper confidence interval bounds

Fixes

• fixed bug with automatic levels in eval_contour()
• correct buckling plate model; now takes wavenumber for buckling mode
• remove dependency on psdr package by inboarding & trimming code, allows us to keep tran_varproj() without a cvxpy dependency
• vectorize the cantilever beam model's functions

Documentation

• add a more informative example in docstring for if_else()
• add documentation to eval_sample() that mentions tran_sp() for reducing model runtime
• add link to random variable modeling page in documentation to undefined copula error

Version 0.3.0

Breaking Changes

• renamed eval_monte_carlo() to eval_sample()
• changed default argument behavior for n in eval_sample(); no longer provides default n=1

Infrastructure Changes

• Moved dependencies from requirements.txt to setup.py
• Changed optional dependencies to fail at runtime, rather than at import. Also moved optional dependencies to main grama namespace.

Features

• Added importance sampling with tran_reweight; effective sample size approximation with neff_is()
• Added active subspace approximation with tran_polyridge()
• Added marginal fitting by the method of moments with marg_mom()
• Added fumulative standard deviation window function cumsd()
• Added plotnine under-the-hood for visualization; plotnine functions available through Grama namespace for convenience
• Re-implemented autoplot utilities using plotnine
• Added contour generation through marching squares with linear interpolation via eval_contour()
• Made Marginal class functions Marginal.l(), Marginal.q(), Marginal.p() symbolic to enable use within tran_mutate()
• Added QQ plot helper qqvals()
• Added grouped counting helper tran_count()
• Added df_group() helper to generate sweeps

Fixes

• Vectorized trajectory model
• Fixed bugs in PRLC model, added unittest coverage

Version 0.2.2

Additions:

• Summary functions gr.skew() and gr.kurt()

Fixes:

• Fix behavior of tran_pivot_longer() when using .value and names_sep simultaneously; no longer have to provide dummy values_to argument.
