In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.The general form of its probability density function is = ()The parameter is the mean or expectation of the distribution (and also its median and mode), while the parameter is its standard deviation.The variance of the distribution is . Here, lambda represents the events per unit time and x represents the time. Logistic regression (aka logit regression or logit model) is a non-linear statistical analysis for a categorical response (dependent variable), which takes two values: 0 and 1 and represents an outcome such as success/failure.
