Method Detail

getCoefficient

public double getCoefficient(int i)

Returns the estimate for a coefficient.

Parameters:

i - an int which specifies the index of the coefficient whose estimate is to be returned.

Returns:

a double which contains the estimate for the i-th coefficient.

getStandardError

public double getStandardError(int i)

Returns the estimated standard error for a coefficient estimate.

Parameters:

i - an int which specifies the index of the coefficient whose standard error estimate is to be returned.

Returns:

a double which contains the estimated standard error for the i-th coefficient estimate.

getTStatistic

public double getTStatistic(int i)

Returns the t-statistic for the test that the i-th coefficient is zero.

Parameters:

i - an int specifying the index of the coefficient whose standard error estimate is to be returned.

Returns:

a double which contains the estimated standard error for the i-th coefficient estimate.

getPValue

public double getPValue(int i)

Returns the p-value for the two-sided test.

Parameters:

i - an int which specifies the index of the coefficient whose p-value is to be returned.

Returns:

a double which contains the p-value for the i-th coefficient estimate.
