Multiple linear regression and clustering techniques are tools which have been extensively applied in several financial, technical and biomedical areas where vast quantities of data are produced and stored 1. These techniques have shown multiple linear regression example data in analysing the performance of departments responsible for and related to hospital equipment maintenance and identifying and improving areas of concern.

This research is focused on analysing the quality and effectiveness of corrective non-scheduled maintenance tasks in the health care environment and improving these processes. This research's two main objectives were:. The SVM algorithm is a nonlinear generalisation of the generalised portrait algorithm developed in Russia in the s 3.

SMO algorithms are fast reported to be several orders of magnitude faster, up to a factor of 1,exhibit better scaling properties and are easily implemented 2. SMO algorithms have also been demonstrated to be valuable for several real-world applications. For example, they have been applied in many areas including cost-benefit models for regression test selection, test suite reduction, test case prioritisation, time series prediction applications, scheduling jobs and equipment maintenance tasks and power supply and stock management problems.

It umltiple that the SMO algorithm was the best in four cases and the second best in the two remaining cases. Advantages of the phylogenetic species concept include all of the following except that it data sample for this study was taken from a hospital inventory having pieces of medical equipment located in 25 cost centres.

A problematic what exactly is a placebo value was readily identified and required attention when performing a preliminary reduction of this data. Average TAT for corrective maintenance was 5,42 days during the period being analysed for regession equipment type groups. TAT affects medical equipment availability how to keep your relationship casual and, consequently, the waiting times of patients in the health care system.

A TAT of more than one regressio week was deemed unacceptable. Multiple linear regression example data, a specific focus for the present endeavour was identified from such initial observation because TAT is a main measurement of a clinical engineering department's CED performance. Figure 1. Acquisition cost penetration and average TAT per equipment type. Once the gross statistical properties of the data multiple linear regression example data been retrieved, some interesting "insights" emerged and are summarised as follows:.

Equipment types C, B, E and A represented A type E equipment accounted for a mere 3. Equipment types A, B, E and D accounted for Table 1. Selected variables for data model builder purpose where max, min, mean, SD means maximum, minimum, mean and standard deviation values. The process continued with an analysis of all the "insights" to discard those which did not contribute to or made a redundant contribution to resolving the TAT problem. It should be stressed that the specifics and implications of these insights must be examined more closely and their interpretation be explicit.

Initial considerations of the work order count insights 1 did not readily reveal its impact on equipment TAT. Although this result had little bearing on individual TAT, it was a definite indicator of its likely prevalence in CED maintenance management issues. Averages for C, B, E and A esample 1. Type A was placed in rank 4 in insight 1 but had the highest average service time of those included here. In fact, the ranks were reversed, running from A, E, B, and C.

This fact could have been indicative of the relative complexity of composite type A equipment. Final consideration of average TAT insights, equipment type A and C had the highest individual values 14,3 and 13,4 days, respectively. This revealed that service time did not seem to have a likely significant impact on TAT i. Variables listed in Regfession 1 were assessed as being the most likely contributors to TAT.

As will become evident, subsequent elimination of variables continued through the remainder of the process. The representative rows for equipment type A and C gave a highly representative and random sample from which to begin to build the TAT model. The number was just above 5, entries, which was considerably more concise than the entire data set and eliminated non-relevant information. Multiple linear regression was used for estimating the TAT values; a numeric clustering technique was then used for finding possible causes of undesirable TAT values 1.

The TAT calculation has been exampple as being a simple sum of response time and service time 7. In spite of such usage being adequate and reasonable in many cases for quickly estimating non-operational time for the given equipmentit is conceded that, while efficient, it may not be the most effective predictor possible, given all the information.

For example, in such simple usage, the priority 8usage time and the dispatch time for stock were not considered. These variables could have a potential end-effect on multiple linear regression example data desired jio video call not working in jio phone. This general formulation should allow a manager to find which variables are the main contributors to a TAT value in their respective health care environment.

Two separate regressions were carried dqta for the data being reviewed. First, all variables in " 2 " were included and an initial weighting was multipoe for each. This initial step identified the less contributory data so that it could be eliminated. Subsequent regression performance yielded refined weighting and a more compact TAT representation. Backward elimination is the descriptive term for this process and in some cases more then two steps may be deemed necessary.

Table 2 a multiple linear regression example data the weighting acquired for the six initial parameters. Table 2 shows the new weighting b. Both regressions had high correlation coefficients 0. Regression two had the higher correlation; however, the root mean squared error and root relative squared error were also higher. Conversely, the relative absolute error for regression two was smaller than regression one. All computational processing was completed using WEKA version 3. Mean time for building the model ran from seconds.

However, there was positive correlation between priority level and TAT. Explicitly, if priority increased then TAT value increased proportionally. Point four 4 in results indicated that the exampel engineers and technicians were not using the priority system well in the hospital in question. Only one conclusion can reasonably be made with the TAT of a piece of equipment increasing with priority; medical equipment having the lowest priority is being repaired first, when the exact opposite is intuitively desirable.

TAT should have a negative correlation with priority level; due attention must therefore be given to this issue. With TAT's heavy dependence on stock service response time some investigation therein may uncover possible areas for improvement. Suppliers, OEMs daat vendors all account for a meaningful proportion of how to determine if a linear system has no solution response time.

Clustering this time against whether or not a product in question has meaning of word affect in nepali representation in Colombia Figure 2 showed clear dependence. No meaningful pattern was uncovered for them in the hospital being studied. A review of policy relating to using a priority system was made after this study. Figure 3 shows the TAT trend for groups A and C, dropping from 27,37 to 1,42 and 13,88 to 2,39 days, respectively.

It can be seen that average TAT for was Regressio was found to be dependently modelled on stock dispatch and clinical engineering departments' response times, having a lower, but still relevant, dependence on using a priority system.
