The Central Limit Theorem (CLT) is a statistical concept that states that the sample mean distribution of a random variable will assume a near-normal or normal distribution if the sample size is large enough. In
The impact of the random variable distribution (Gauss or Lognormal) describing soil stiffness on foundation deposits was assessed. The Monte Carlo simulation method was applied in the computations. The settlements of the strip foundation with the subsoil described by a single random variable and a ...
. The most commonly used regression model, the ordinary linear regression, models y as a normal random variable, whose mean is linear function of the predictors, b0 + b1*x1 + ... , and whose variance is constant. In the simplest case of a single predictor x, the model can be ...
In fact, a general method of constructing such a transformation does exist, although not as simple as just exponentiation. By definition, applying the normal CDF (denoted here by PHI) to a standard normal random variable results in a r.v. that is uniform on the interval [0, 1]. To see...
for values of that are smaller or larger than . On the contrary, the probability density function of a standard normal random variable is almost zero at . As a consequence, if we use a standard Monte Carlo approximation: we extractlots of valuesof ...
The normal distribution is a continuous probability function and is given by the formula: Where: μis the mean of the distribution σ2is the variance xis the independent variable for which you want to evaluate the function How to use the NORM.INV Function in Excel?
The expected value of a discrete random variable is the product of the probability and the number of trials. Therefore, if the probability of an event happening is p and the number of trials is n, the expected value will be n*p. Is the expected value the same as the expecte...
I have tried to test the normal distribution of my sample (one of my questionnaires with 24 questions and a sample of 457) with Shapiro.test in R; however the result in p-value = 9.093e-07 and apparently not normal distribution. I wonder how I can change it to a normal distribution....
