*'X' is the value for which distribution is evaluated and df is the number of degrees of freedem.
==Description==
*This function gives the one_tailed probability of the chi-squared distribution.
*It is denoted by X^2 distribution.Normally categorical datas may displayed in tables.
*The X^2 static used to compare the observed value in each table to the value
*which would be the expected under the assumption. The conditions of X^2 test is
1.The table should be 2x2 or more than 2x2
----
2.Each observations should not be dependent
<div id="1SpaceContent" class="zcontent" align="left">
3.All expected values should be 10 or greater.
The test statistic is:
X^2=summation(Oi-Ei)^2/Ei
The degrees of freedom are: (r–1)(c–1)
r =No. of rows and c = No. of columns
Where:
Oi-the observed value in the ith cell
Ei- the expected value in the ith cell
Also this function will the result as Error when
1.The x&df values are nonnumeric
2.The x value is negative or df value is not an integer
3. The df <1or df>10^10
4.Here CHIDIST=P(X>x),where X is a X^2 random variable.
