Fathers who are secondary to a female caregiver were more engaged as thinkers and planners. But men raising a child without a female partner were found to have the same level of emotional response as a mother and the same thinking and planning response as the secondary father.
In statistics and probability theory, triangular distribution is a continuous probability distribution. The probability density function of a triangular distribution is shaped like a simple geometric shape, triangle. The triangular distribution is a good model for skewed distributions. It has a definite lower and upper limit, which is helpful to avoid unwanted extreme values.
Beta distribution. In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval, 1] parametrized by two positive shape parameters, denoted by Î± and Î², that appear as exponents of the random variable and control the shape of the distribution.
