To analyze skewed data, skew normal distribution is proposed by
Azzalini (1985). For practical problems of estimating the skewness parameter
of this distribution, Gupta and Gupta (2008) suggested power normal distribution
as an alternative. We search for another alternative, named tilted
normal distribution following the approach of Marshall and Olkin (1997) to
add a positive parameter to a general survival function and taking survival
function is of normal form. We have found out different properties of this
distribution. Maximum likelihood estimate of parameters of this distribution
have been found out. Comparison of tilted normal distribution with
skew normal and power normal distribution have been made.
