SISA

SISA is a simple Interactive Statistical Analysis for PC (DOS) i.e. for the Windows operating system from Daan Uitenbroek. There is an
excellent collection of individual windows and DOS modules for several statistical calculations, including some analyses not readily available elsewhere.

Download SISA Windows Program

These Windows programs contain a certain procedure that performs specific statistical analysis.

  • lifetables
    It helps to perform Mortality Analysis for Demography and Epidemiology. The Lifetables program calculates the life expectancy, including all intermediary statistics, variance a confidence interval for the life expectancy, Potential Gains in Life Expectancy (PGLE), Years of Potential Life Lost (YPLL), and Lifetime Years of Potential Life Lost (LYPLL).
  • Distributions
    The SISA-Distributions program allows the user to analyze discrete single-dimension distributions. The program is based on various manipulations of the Poisson, binomial, and hypergeometric distribution. Available are the probability of an observed number of cases for the certain null hypothesis, the calculation of exact Poisson, binomial, or hypergeometric confidence intervals, the exact and approximate size of a population using catch-recatch methodologies, the full analysis of a Poisson distributed rate ratio, Fieller analysis, and two versions of the negative binomial distribution can be used in various ways.
  • Multinomial
    The multinomial program is the exact solution to the Chi-square Goodness of fit test of testing for a difference between an observed and an expected distribution in a one-dimensional array. For the two-category array, the multinomial test provides a two-sided solution for the Binomial test. The multinomial allows you to work with empty ‘0’ observation cells although you must expect a cell.
  • Tables
    SISA-Tables is a program for the analysis of tables with up to 2*7 and 3*3 cells. This program (Tables) allows for exact and approximate
    statistics. Fisher exact, Number Needed to Treat, Proportional Reduction in Error Statistics, Normal Approximations, Four different Chi-squares, Gamma, Odds-ratio, t-tests, and Kappa are among the many statistical procedures available in Tables Program.
  • Weighting
    The weighting program by SISA calculates sample weights according to the cell weight procedure. The design factor and the effective sample size for the resulting set of weights are determined. It is possible to specify a value above which extreme weights will be trimmed. The not-trimmed weights will be recalculated.
  • Intra Correlation
    The intra-correlation program from SISA calculates intra-correlations and design effects for clustered samples where the outcome measure is
    the number of positive responses per cluster. Confidence intervals and other statistics corrected for design effects can be calculated.
    This program helps to compare two groups of clusters with a t-test procedure.

Spreadsheets

There are two spreadsheets available, a spreadsheet that does demographic analysis and another spreadsheet for the calculation of intracorrelation coefficients. The spreadsheets are in Microsoft Excel file format; If you have MS Excel installed on the computer, your computer will start up Excel and load the spreadsheet into Excel automatically after you double-click the procedure name.

  • Lifetable
    This lifetable spreadsheet does a full abridged current life table analysis to obtain the life expectancy of a population. Furthermore, one can calculate Potential Gains in Life Expectancy (PGLE) after removing cause k, considering competing causes of death; the (Premature) Years of
    Potential Life Lost (YPLL), the Standardized Mortality Ratio (SMR), standardized numbers per 100,000, and the Comparative Mortality Figure (CMF) can also be calculated.
  • Discounted YPLL
    This spreadsheet contains the procedure to discount the YPLL if you only have mortality by age.
  • Intra Correlation
    The spreadsheet performs intra-correlation calculations for dichotomous (binary yes/no) type outcome variables according to two different
    methods proposed for the single cluster one by Fleiss and another one by Bennett et.al. A third spreadsheet concerns a method for two clusters by Donner and Klar.
  • Distributions
    22 spreadsheets demonstrate various statistical distributions such as Beta, Binomial, Normal, Poisson, Pareto, etc.

MS-DOS Programs

The programs below are for use on MS-DOS (DOS Command Prompt). These DOS procedures (programs) are no longer maintained, except for bug fixing, and generally, have limited statistical capabilities. The DOS procedures are very fast as compared with the HTML/Javascript programs on the Website and are also very small in size.

  • Hypergeometric
    This procedure calculates the hypergeometric probability distribution to evaluate the hypothesis with sampling without replacing in small populations i.e. (hypergeometric distribution)
  • Binomial
    This procedure calculates probabilities for sampling with replacing in small populations or without replacing it in a very large population. It Can be used to approximate the hypergeometric distribution.
  • Poisson
    This procedure calculates probabilities for samples that are very large in an even larger population. it can used to approximate the binomial distribution.
  • Negative Binomial 1
    It is used to study accidents, and is a more general case than Poison, it considers the probability of getting into accidents if accidents
    clusters differently in subgroups of the population.
  • Negative Binomial 2
    Another version of the negative binomial, this one is used to do the marginal distribution of binomials. Often used to predict the
    termination of real-time events. Such as the probability of terminating listening to a non-answering phone after n-rings.
  • Multinomial
    Same as described above in Windows Programs.
  • Fisher
    Is used to calculate the exact p-value for 2*2 contingency tables. Use the Fisher exact instead of the Chi-square when you have a small value in one cell or a very uneven marginal distribution.
  • SPRT
    This Dos procedure is not often used, but it is quite good. This procedure is based on the case of phenomena
    being observed, tested, or data collected, sequentially in time. It is sometimes used in medical trials to monitor the amount of
    negative side effects and to decide whether the trial should be stopped as the number of side effects is considered high enough.
  • Chi-Square
    This Dos procedure calculates the Chi-square and some other measures for two-dimensional tables.
  • Casro
    This Dos Program calculates response rates according to different procedures. The CASRO (Council of American Survey Research Organizations)
    the procedure is the “accepted” procedure for surveys.
