This has been corrected so that Odds Ratios are plotted.Ģ. When solving for OR1 & P1 and using Odds Ratios for the input type, the Y-axis values on the plots were labeled as Odds Ratios, but plotted as proportions. Fixed the Tests for Two Proportions in a Repeated Measures Design procedure. Mortality 1 Until T0 was not updating when changing Median Survival Time 1 or Hazard Ratio 1.ġ. Fixed a problem in the Survival Parameter Conversion Tool. The detail reports for these two procedures were also corrected to display appropriate values.Ģ. PASS was calculating hazard rates for each row as though all previous survival proportions (or mortalities) were equal. The procedures were not calculating the hazard rates correctly when using spreadsheet entry for the survival proportions or the mortality rates. Fixed an error in the Logrank Tests (Input Proportion Surviving) and Logrank Tests (Input Mortality) procedures. In some cases the power was being drastically underestimated for the Skewness test.ġ. Corrected error in Normality Tests procedure. The calculations in PASS and the validation results have been updated to reflect the author’s corrections.Ģ.
#NCSS PASS 14 KEYGEN SOFTWARE#
The author of the paper on which this procedure is based discovered a calculation error in his software used to create the results in the paper. Fixed power calculation error in Tests for Two Correlated Proportions in a Matched Case-Control Design. The message for R (Accrual Time) indicated that 0 was a valid entry, but R must be greater than 0 in this procedure.ġ. Corrected mouseover message error in the Logrank Tests Accounting for Competing Risks procedure. The type of input was mislabeled in some cases.Ģ. Corrected summary statement errors in the Logrank Tests procedure output. Corrected a “Subscript out of Range” error in Hotelling’s One-Sample T2 procedure that occurred when the language setting on the machine uses a comma as the decimal.ġ. Corrected an error that caused incorrect power and sample size calculations when entering “R1” in the Tests for Two Proportions in a Stratified Design (Cochran/Mantel-Haenszel Test) procedure when the computer’s system language setting was set to a South African language setting or any other language setting where R is a currency symbol.ģ. The correct input power value is now used.Ģ. When solving for Sample Size, the target power value was being set to 1-(User-Entered Value for Power). Corrected an error in the Multiple Contrasts (Simulation) procedure. The period was incorrectly being replaced by a comma in non-numeric instances.ġ. in “D0.L”) when the computer language uses a comma as the decimal symbol. Corrected issues encountered in various procedures where the period is used in a way other than to represent a decimal symbol (e.g. Fixed documentation typos in the Non-Central Chi-Square Distribution in the Probability Calculator documentation.ġ. The power was not being calculated correctly in some cases when the group sample sizes are unequal.ģ.
Fixed power calculation error in the Tests for Two Variances procedure.
#NCSS PASS 14 KEYGEN UPDATE#
This correction returns the PASS calculation results for the Tests for Two Correlated Proportions in a Matched Case-Control Design procedure to the same results obtained prior to PASS 14 update 14.0.10.Ģ.
The calculations in PASS have been updated to reflect the author’s corrections. The author of the paper on which this procedure is based determined that the correction made in PASS 14 update 14.0.10 was unnecessary. Fixed power calculation error in the Tests for Two Correlated Proportions in a Matched Case-Control Design procedure. Fixed a “Subscript out of range” error in the Tests for Two Proportions in a Repeated Measures Design procedure that occurred when Group Allocation was set to “Enter total sample size and percentage in Group 1” and Definitions were being output in the report.ġ.
This page lists the changes that have been made to PASS 14 since it was released.
