I have replaced the chassis/dash air compressor on my 2014 Fleetwood Discovery. The ac switch does not light up nor does the compressor come on or cycle. Freightliner says there are two fuses: 5 and 7.5 that control these. They could not say where they located. I have found the following fuse boxes but none contain these two fuses that I saw.
The Ljung–Box test (named for Greta M. Ljung and George E. P. Box) is a type of statistical test of whether any of a group of autocorrelations of a time series are different from zero. Instead of testing randomness at each distinct lag, it tests the "overall" randomness based on a number of lags, and is . See moreThe Ljung–Box test may be defined as:$${\displaystyle H_{0}}$$: The data are independently distributed (i.e. the correlations in the population from which the sample is taken are 0, so that any observed .

The Ljung-Box statistic, also called the modified Box-Pierce statistic, is a function of the accumulated sample autocorrelations, r j, up to any specified time lag \(m\). As a function of .The Ljung (pronounced Young) Box test (sometimes called the modified Box-Pierce, or just the Box test) is a way to test for the absence of serial autocorrelation, up to a specified lag k.
The test is closely related to the Ljung & Box (1978) autocorrelation test, and it used to determine the existence of serial correlation in the time series analysis. The test works with chi-square distribution by the way.The asymptotic distribution of the Box-Pierce and Ljung-BoxQ tests is derived under the assumption that {y t } is serially independent. This distribution result
Box-Pierce and Ljung-Box Tests Description. Compute the Box–Pierce or Ljung–Box test statistic for examining the null hypothesis of independence in a given time series. These are .
The point exactly is that without strict exogeneity, the Box-Pierce/Ljung-Box do not have an asymptotic chi-square distribution, this is what the mathematics above show. Weak exogeneity (which holds in the above .In this paper, a block bootstrap procedure is used to estimate the distribution of the QK statistic when the data are uncorrelated but dependent. The paper presents the results of a Monte . A test to determine whether a time series consists simply of random values (white noise). The test statistic is Qm, given by , where r is the sample autocorrelation at lag l, m is .

The point exactly is that without strict exogeneity, the Box-Pierce/Ljung-Box do not have an asymptotic chi-square distribution, this is what the mathematics above show. Weak exogeneity (which holds in the above model) is not enough for them.In this paper, a block bootstrap procedure is used to estimate the distribution of the QK statistic when the data are uncorrelated but dependent. The paper presents the results of a Monte Carlo investigation of the numerical performance of this bootstrap procedure. Under these conditions the Ljung-Box $Q$-statistic (which is a corrected-for-finite-samples variant of the original Box-Pierce $Q$-statistic), has asymptotically a chi-squared distribution, and its use has asymptotic justification.The Ljung–Box test (named for Greta M.
