Statilite [pictured on the left] can compute a number of common neuropsychological statistics.

  1. 1x2
    • Chi-squared, 1 & 2-tailed binomial probability
    • Null hypothesis: outcomes are equiprobable.
  2. 2x2
    • Chi-squared; 1 & 2-tailed Fisher's exact test; Liebermeister's Measure; Lancaster's Mid-P. Lancaster Mid-P quasi-exact test (1961) and Liebermeister's 1877 quasi-exact test (Seneta and Phipps, 2001; Phipps, 2003) are more accurate and powerful in situations without fixed marginals.
    • Null hypothesis: the two groups have the same probability of falling into the category 'Condition 1' or 'Condition 2'.
  3. D' [D-prime]
    • Computes sensitivity measures D', A'
    • Computes criterion measures Beta, B and C.
    • Compares confidence intervals of D' and C between two observers.
  4. Right triangles
    • Computes viewing coordinates (adjacent, opposite and viewing angle).
    • E.G. A circle of 7 cm viewed from a distance of 50 cm will subtend 7.97 degrees (when the observer is looking at the edge of the circle).
  5. Oblique triangles
    • Computes lengths and angles of triangles using sine and cosine laws. Given angles [A] and/or sides [S] missing values can be derived from SSS, SAS, AAS and ASA.
  6. Coreg
    • Converts between Talairach space and neurological slices.

XLGen works Microsoft Excel to provide rapid data analysis.

  1. Discrete data: Fisher's exact test, Mantel-Haenszel Chi-squared.
  2. Continuous data: Mean, standard deviation, kurtosis, skew, median, 1st & 3rd quartiles, confidence intervals.
  3. Data filtering: 1.5 Interquatile range exclusion.
  4. Two-way comparisons: T-tests (related and unrelated), F-tests.
  5. ANOVA: Up to 3 factors, repeated or unrepeated designs.
  6. Regression: linear and non-linear regression. Computes R-squared.
  7. Exports results to clipboard for inclusion in Excel or a word processor.
