NCS_ANOCOV1

Calculates the elements of an analysis of covariance (ANOCOV) table.

NCS_ANOVA_ONE1

Calculates the elements of a one-way ANOVA table.

NCS_ANOVA_TWO1

Calculates the elements of a two-way ANOVA table with no replications.

NCS_ANOVA_TWO2

Calculates the elements of a two-way ANOVA table with replications.

NCS_BARTCHI1

Calculates the Bartlett Chi-square statistic for an array of sample variances.

NCS_BEHRENS1

Implements the Behrens-Fisher test for paired and unpaired arrays.

NCS_BEST_LR1

Finds the best linearized regression for a set of user-selected transformations.

NCS_CONTABLE1

Implements n k contingency table calculations.

NCS_CRESFIT1

Implements nonlinear regression.

NCS_DAP1

Calculates the statistics related to differences among proportions.

NCS_INTRACLASS1

Calculates the intraclass correlation coefficient for a table of k n observations.

NCS_KENDALL1

Calculates the Kendall concordance coefficient for a matrix of rank values.

NCS_KRUSKAL1

Implements the Kruskal-Wallis test to determine if several groups of ranked data belong to a single population.

NCS_LATIN_SQR1

Calculates the elements of a Latin square ANOVA table.

NCS_LR1

Implements linear regression with post regression ANOVA table and additional statistics.

NCS_LR2

A version of NCS_LR1 that supports weighted data.

NCS_MA1

Calculates the moving average for a set of observations.

NCS_MA2

Calculates the moving average for a set of observations. Also calculates the standard deviation, the confidence interval for the moving average, and the confidence interval for the standard deviation.

NCS_MANN1

Calculates the Mann-Whitney test statistic for an array of paired or unpaired ranked values.

NCS_MEANSSDF1

Implements the mean-square successive difference statistic to test the randomness of an array of values.

NCS_MLR1

Implements multiple linear regression between three variables.

NCS_MLR2

Implements multiple linear regression between two variables.

NCS_MOMENTS1

Calculates statistical moments.

NCS_MOMENTS1

Calculates statistical moments for weighted data.

NCS_PAIRED1

Implements the Student-t test for the means of paired data.

NCS_POLY1

Implements quadratic regression between two variables.

NCS_RANKER1

Calculates the numeric ranks for an array of values.

NCS_SPEARANK1

Calculates the Spearman rank correlation coefficient for an array of paired ranked values.

NCS_UNPAIRED1

Implements the Student-t test for the means of unpaired data.

New Features

Many programs in the NCS35TB Stat Pac implement legacy statistical programs found in the Stat Pacs of the HP-65, HP-67, and HP-41C calculators. The implementation for the HP-35s, which is written from scratch, takes advantage of the new features of the calculator. The highlight of these new features is the ability to store data in the unnamed registers, using indirect addressing. Some programs store the raw data, while others store the statistical summations. In the latter case, the programs allow you to access the statistical summations for the various data groups to further add or remove data. Either approach is new in the Stat Pac and makes use of the rich number of unnamed registers. The various programs also store data as 2D or 3D vectors to further economize data storage.

Consistent Interface

The programs in the NCS35TB Stat Pac have a consistent user interface. The following labels perform similar tasks in all the programs:

 

       XEQ I initializes the program.

       XEQ A adds data.

       XEQ D deletes data.

       XEQ E edits data.

       XEQ C performs statistical calculations.

       XEQ U displays the name of the program.

Documentation

The NCS35TB Stat Pac comes as a PDF-formatted manual that is about 440 pages long. Delivery occurs via email and requires email addresses that can accept attachments that are about 4MB in size.

 

The manual has sections for each program that present the following information:

 

       A brief introduction for the program and its features.

       A brief presentation of the equations used in the statistical calculations.

       Instructions for using the program.

       A list of labels and program variables used by the program.

       A commented listing for the program.

       An example for using the program.
