      Variability in the Population-the standard deviation is the most usual measure and often needs to be estimated-more variability the less accurate the estimate and the larger the sample size required Confidence Level-how certain you want to be that the population figure is within the sample estimate and its associated precision-higher the ...

      -1 is the inverse of the cumulative standard normal distribution function, often referred as probit or normit, and . Φ. is the cumulative standard normal distribution function. The probit regression model can be viewed also as a special case of the generalized linear model whose link function is probit. 2.3 Complementary log-log
