Allowable Skew Coefficient When Computing an Expected Probability Curve
When using the Compute Expected Probability Curve Using Numerical Integration (EMA) option, the allowable range for the skew coefficient was +/- 1.2. If the adopted skew coefficient magnitude was found to be greater than 1.2, an error was thrown and the compute was halted. Now, the allowable skew coefficient has been expanded to +/- 1.414 (Bobee, 1991) and only a warning will be issued within the Report file.
Bugs Fixed
The following bugs were present in previous versions and have been fixed within version 2.3.1.
Distribution Fitting Analysis Confidence Limits and Expected Probability Curves
In previous versions, confidence limits and expected probability curves computed within the Distribution Fitting Analysis were truly random and not reproducible. The computed confidence limits and expected probability curves for two analyses with the same dataset, distribution, and distribution fitting method were different. Confidence limits and expected probability curves are now pseudo random and reproducible for a given dataset, distribution, and distribution fitting method combination. This bug was introduced in v2.2 and fixed within v2.3.1.
Variable Time Window Option Doesn't Include Perception Thresholds Prior to Start of Systematic/Historical Data
In previous versions, when using the variable time window option within the Bulletin 17 analysis, perception thresholds that were entered prior to the start of the first systematic or historical event were not included in the analysis. This issue has been rectified such that all data is incorporated when using the variable time window compute option. This bug was introduced in v2.3 and fixed within v2.3.1.
Selecting a Data Set Prior to Entering an Analysis Name Causes an Error When Re-Opening a Study
Selecting a Data Set prior to entering a Name in the Bulletin 17, General Frequency, Volume Frequency, Balanced Hydrograph, Duration, or Distribution Fitting analyses caused an error when the study was re-opened. Users must now enter a Name prior to selecting a Data Set in these analysis types. This bug was introduced in v2.3 and fixed within v2.3.1.
Correlation Analysis Drops Name, Description, DSS File Name, and Report File Fields After Successful Compute
In previous versions, the Correlation Analysis would occasionally drop user-entered information (e.g., Name, Description, DSS File Name, Report File, and location information) after a successful compute. This bug was introduced in v2.3 and fixed within v2.3.1.
